SYNOPSIS
OµS’15 is the 6th edition of the international conference wholly dedicated to optical microsystems organized by the European Optical Society (EOS) and the Italian Society of Optics and Photonics (SIOF), Italian Branch of the EOS.
An optical microsystem can be defined as a complex system, able to perform one or more sensing and actuation functions, taking advantage of the progress in micro- and nano-technologies to integrate in a smart way optical devices with electronic, mechanical and sensing components. The increasing interest in this field arises from the perspective applications that would significantly improve the quality of life. The list of possibilities offered by these enabling technologies is very long and seems to increase day by day. Optical microsystems are finding applications not only in ICT, but also in biotechnologies, medicine, food and environmental monitoring, aerospace and automotive, homeland security, etc.
The conference programme will focus on fundamental as well as more applied topics. Biosensors, biochips and lab-on-chip, microfluidic and optofluidic systems, non-linear and quantum optical devices, silicon-based optoelectronics and MOEMS, chemical and physical optical microsensors, new characterization methods for materials and devices, novel imaging techniques, biomimetic devices and systems are among the hot topics of the conference.

PLENARY SPEAKERS
Thursday, 17 September 2015
10:10>10:50 Optical-Antenna-Enhanced Spontaneous Emission Eli Yablonovitch, University of California (USA)
Pagano, Hotel La Palma
Antennas emerged at the dawn of radio for concentrating electromagnetic energy to a small volume << λ3, allowing for nonlinear radio detection. Such coherent detection is essential for radio receivers, and has been used since the time of Hertz.
Conversely, an antenna can efficiently extract radiation from a sub-wavelength source, such as a small cellphone.
Similarly antennas can accelerate spontaneous emission from a small quantum dot or molecule, whose emission rate can become faster than stimulated emission. Antennas interact equally with real electromagnetic fields, as well as quantum zero-point field fluctuations that are responsible for spontaneous emission.

10:30>11:10 Efficient visible photoluminescence from silicon nanostructures Leigh Canham, PSiMedica Ltd (UK)
Pagano, Hotel La Palma
Nanostructuring the semiconductor silicon can dramatically change its properties. I will review progress over the last 25 years in optimizing and understanding its efficient visible luminescence. Quantum confinement effects and optimized surface passivation can produce tunable wavelengtth photoluminescence of remarkably high quantum efficiency. Some other remarkable properties of “nanosilicon” will also be mentioned that are relevant to microchip-based systems, medicine and consumer products.

11:20>11:50 Modern concepts for sensing molecular interactions
Antonio Varriale, Maria Strianese, Alessandro Capo, Angela Pennacchio, Maria Staiano and Sabato D'Auria (Institute of Food Science, Consiglio Nazionale delle Ricerche, Avellino, Italy) Pagano,
Hotel La Palma
The function of a protein is largely mediated through its interactions with other molecules. Consequently, molecular interactions are responsible of the regulatory processes of cellular functions. Hence it is of critical importance the mapping of protein-protein interactions. We will highlighting the progress that has been achieved in our labs for advanced sensing molecular interactions.
11:20>11:50 Group IV Mid-IR Photonics
Goran Mashanovich (University of Southampton, Optoelectronics Research Centre, United Kingdom) Relais,
Hotel La Palma
In this paper several Si and Ge mid-IR (MIR) photonic devices are reported. It is shown that SOI is a viable platform for wavelengths up to 4 m. For longer wavelengths, suspended Si platform is a good candidate and a novel approach that employ only one dry etch step is presented. For even longer wavelengths, Ge is the best candidate. Record low loss Ge-on-Si passive devices have been fabricated. All optical modulation has been achieved in Ge, and two photon absorption experiments conducted.

08:30>09:00 Key Enabling Technologies in the new concept of Smart Living P. Siciliano, A. Leone and L. Francioso (CNR IMM, Italy)
Pagano, Hotel La Palma
This work refers to the use of Key Enabling Technologies for the development of advanced technological solutions for the realization of products (sensors, devices, etc.) and services which, according to a pattern of "Ambient Assisted Living"
and "Ambient Intelligence", enable to redesign the sense of “Smart Living” to ensure inclusion, safety, welfare, comfort, care, health care, environmental sustainability.
14:30>15:00 Holographic sensors: advances, challenges and applications Izabela Naydenova (Dublin Institute of Technology, Ireland) Relais,
Hotel La Palma
Holographic sensors are three-dimensional nanostructures created in functionalized polymers or natural organic polymer matrices that are sensitive to chemical or physical stimuli. This paper reviews the fabrication strategies for holographic sensors and describes holograms, which are sensitive to different chemical analytes and pressure.
16:30>17:00 Coherent Raman Scattering Microscopy
Martin Winterhalder and Andreas Zumbusch (University of Konstanz, Germany) Pagano,
Hotel La Palma
Coherent Raman Scattering (CRS) microscopy is a label free approach which provides an attractive complement to fluorescence based methods. While it does not feature the high sensitivity of fluorescence microscopy, its contrast generation based on vibrational molecular spectra circumvents both the labeling and the photobleaching problem. We will present the principles of CRS microscopy and highlight biological and material scientific applications.
16:30>17:00 Photonics-enhanced multifunctional polymer optofluidic chips
Heidi Ottevaere, Diane De Coster, Tom Verschooten, Jürgen Van Erps, Michael Vervaeke and Hugo Thienpont (Vrije Universiteit Brussel, Belgiom)
Relais,
Hotel La Palma
We will touch upon various polymer-based micro-optical detection systems. For each system we will present the complete development process from optical design, to fabrication and proof-of-concept demonstration. We have created designs with a high sensitivity but yet with a relatively simple layout to ensure their manufacturability and robustness paving the way towards multifunctional, low-cost and portable lab-on-a-chip systems.

09:00>09:30 Opto-fluidics: do we really need only “new” materials for getting smart and fully integrated devices?
Cinzia Sada (University of Padova - Physics and Astronomy Department, Italy) Pagano,
Hotel La Palma
Opto-Microfluidics holds great promise to develop a lab-on-chip system that integrates different functionalities with applications to the chemical synthesis, biological analysis and optical sensing. Most of the challenges rely on the exploitation of materials hosting fully integrated stages. New perspectives will be presented on the use of "old" materials, such as lithium niobate and glasses, in comparison to "new" ones, with a special focus on particle manipulation and

09:00>09:30 Moving from photonics to microphotonics: The case in spacecraft engineering Iain McKenzie (Optoelectronics Section (TEC MME), European Space Agency) Relais,
Hotel La Palma
09:50>10:20 Towards a two-photon multimode fiber endoscope
Christophe Moser, Edgar Morales, Salma Farahi, Demetri Psaltis and Ioannis Papadopoulos (EPFL, Switzerland)
Pagano, Hotel La Palma
Mode control of a multimode fiber has been shown by manipulating cw light with a spatial light modulator. However, propagation of a light pulse suffers additionally from time broadening due to modal dispersion. We present a method to selectively excite specific modes that allows the transmission of a femtosecond pulse.
11:20>11:50 Quantitative phase-digital holographic microscopy: a promising imaging technique to identify new cellular biomarkers of diseases
P. Marquet, K. Rothenfusser, P. Jourdain, C. Depeursinge and P. Magistretti (Ecole polytechnique Fédérale de Lausanne, Switzerland)
Pagano, Hotel La Palma
Quantitative phase microscopy has recently emerged as a powerful label-free technique in the field of cell imaging allowing to non-invasively monitor various cell parameters by measuring the phase retardation of a light wave when transmitted through the observed cells. Practically Quantitative phase-digital holographic microscopy, thanks to its numerical flexibility facilitating parallelization and automation processes, represents an appealing imaging modality to identify new cellular biomarkers.
11:20>11:50 Q-plates and their applications: an overview Lorenzo Marrucci (Università di Napoli Federico II, Italy) Relais,
Hotel La Palma
I will review the main applications of the q-plate demonstrated since its introduction. Q-plates are used for generating and manipulating vector-vortex beams, polarization singularities, and nodal optical areas. The generated photonic states can have tailored rotational properties, useful for applications ranging from quantum communication to angular metrology.
Among the most striking recent results is the recent demonstration of Möbius strips of optical polarization.
14:30>15:00 New methods for labelfree optical computed tomography of live cells Natan T. Shaked and MorHabaza (Tel Aviv University, Israel)
Pagano, Hotel La Palma
We review our new approaches for label-free three-dimensional refractive-index imaging of live cells based on interferometric computed tomography. These methods do not require anchoring the sample to a rotating stage nor are they limited in angular range, and thus allow accurate and noninvasive three-dimensional imaging of cells in suspension without using external contrast agents.
14:30>15:00 Engineering polymer micro and nanoparticles with controlled size, composition and morphology by microfluidics-assisted emulsification
Christophe Serra (University of Strasbourg, France) Relais,
Hotel La Palma
Most conventional processes for the production of polymer particles imply heterogeneous polymerization processes or precipitation processes in a non-solvent. Although these processes lead to polymer particles having a different size domain, the size is very sensible to the operating parameters and cannot readily be adjusted. Here we present our latest developments on microfluidic processes for the production of sized-, composition- and morphology-controlled polymer micro and nanoparticles.
15:40>16:10 Biological Cells Tomography by Digital Holography: A short review
Christian Depeursinge (King Abdullah University of Science & Technology Thuwal, Saudi Arabia) Pagano,
Hotel La Palma
In this presentation we present a short review of our works and other works as well regarding tomographic imaging of dielectric object, biological cells in particular. The complex electromagnetic wavefield scattered by the specimen, can be obtained by reconstruction of digital holograms or by other methods described as Quantitative Phase Imaging. This approach leads to a growing modality in microscopy, which will find its own path in addition to intensity based imaging

17:10>17:40 Learning from examples in optical imaging systems Demetri Psaltis (EPFL, Switzerland)
Pagano, Hotel La Palma
We show that we can learn the shape of an object from examples formed by reconfiguring the optical system. We demonstrate this modality by constructing a neural network that models the optical system and training the network to match the experimentally measured data. The variables of the trained network yield the image of the unknown object at the end of training phase.

09:00>09:30 Multi-dimensional Displacement Measurement based on signal separation using Holographic Interferometry
Pramod Rastogi (Ecole polytechnique Fédérale de Lausanne, Switzerland) Pagano,
Hotel La Palma
This talk will encompass the latest trends and developments in multi-dimensional displacement measurement techniques in holographic interferometry using high resolution methods in signal processing. Experimental results and the statistical performance of the algorithms will be presented when applied to a multi-wave holographic interferometry setup for the simultaneous measurement of in-plane and out-of-plane displacements on a deformed object submitted to load.
09:00>09:30 New developments in lithium niobate nanophotonics
Maria-Pilar Bernal, Abdoulaye Ndao, Wentao Qiu, Nadège Courjal, Gwenn Ulliac, Roland Salut, Fadi I. Baida and Venancio Calero (CNRS FEMTO-ST, France)
Relais,
Hotel La Palma
The optics community has used since decades lithium niobate (LN) material. Due to its multiphysical nature it is straightforward to imagine a LN chip in which thousands of optical functions are integrated. I will present our work in order to achieve this goal. Different active LN nanoophotonic functions will be presented. The possibility of using LN thin films has allowed us to improve the performances. Tunable Fano LN photonic crystals attached to a fiber for sensing will be demonstrated.
09:30>10:30 Simultaneous 3-D visualization and position tracking of optically trapped particles using optical diffraction tomography
Yongkeun Park (Department of Physics, KAIST, Republic of Korea) Pagano,
Hotel La Palma
We present a combined system employing optical diffraction tomography and holographic optical tweezers capable of simultaneous 3-D visualization of the shapes and tracking positions of trapped microscopic samples. We demonstrated the manipulation of a silica bead toward a white blood cell having complicated internal structures, and the tomographic measurements of 3-D dynamics of the white blood cell as it responded to an approaching glass bead in the high acquisition rate.

SYNOPSIS
New properties in nanoscale structures can be dramati-cally tuned with size and shape of the nanostructures. Completely different optical behaviors are produced compared to the bulk counterparts, such as narrow line widths for emission, solar energy conversion, etc. Indeed materials and applications require strong effort to develop spectros-copy and microscopy tools allowing visualization and manipulation of optical properties with nanoscale resolution.
Optics at Nanoscale is a Topical Meeting that covers a spectrum from applied to basic research of this domain providing a forum for all the aspects with the purpose of advancing the state-of-the- art of nanoscale optics.

The development of advanced photonic circuits working in the visible light promises a revolution in a broad range of areas from bio-chemical sensing to quantum computing. We present here the first printed active photonic crystals with embedded quantum dots, fabricated by a powerful route, for nanolaser applications. This work represents a powerful and cost-effective route for the development of numerous nanophotonic structures and devices that will lead to the emergence of new applications.

We will discuss spin-orbit coupling in optical waves interacting with plasmonic nanostructures. Spin-dependent directional excitation of guided modes, inverse spin-Hall effect and spin-controlled optical forces associated with unusual transverse spin of surface waves will be discussed.
15:00>15:30 Mapping optoelectronic processes at the native length scale in organic and inorganic nano composites
Alexander Weber-Bargioni (Molecular Foundry, LBNL, California) Hotel
La Residenza
Here we present insight into the local exciton transport through organic and inorganic semiconducting nano building block assemblies using state of the art near field optics, hyperspectral mapping, conductive AFM and photo Scanning Tunneling Microscopy. Controlling individual excitons and their deliberate movement through a material will provide the access to a new parameter space for the development of next generation light harvesting materials. E.g. with such control the captured energy in form of an excitons could be transported to predetermined sites in the material where the energy can be efficiently harvested. However, the lack of spatial resolution has so far prevented the insight needed to control the transport of optically excited electronic states at their native length scale. Using nano optics, modified confocal microscopy and scanning probe microscopy we study exciton transport through three model systems: Inorganic nano wires, 2-D assemblies of inorganic nano crystals, and through organic PV materials.

Hotel La Residenza
Pulse compression in a dispersive nonlinear crystal with a random size and distribution of the anti-parallel orientated domains is observed via transverse second harmonic generation. The dependence of the transverse width of the second harmonic trace along the propagation direction allows the determination of the initial chirp parameter of ultra-short pulses down to 30 fs via single-shot transverse auto-correlation method.

We propose an efficient and intuitive formalism (valid for lossy and dispersive resonators) to describe light scattering by a resonant metallic nanostructure. We apply it to various problems in quantum plasmonics, plasmonic sensing and spatial coherence in complex media.
11:20>11:50 Plasmonic materials and metamaterials manufactured utilizing directional solidification Dorota Pawlak (Institute of Electronic Materials Technology, Poland)
Hotel La Residenza
Two novel bottom-up manufacturing methods for nanoplasmonic materials and metamaterials will be presented: (i) method based on directionally-grown self-organized eutectic structures; and (ii) NanoParticles Direct Doping method (NPDD) based on directional solidification of dielectric matrices doped with various nanoparticles. In both of these methods we can easily use all available resonant phenomena to develop materials with unusual electromagnetic properties.
12:35>13:05 Measuring polarization of light with nanoantenna arrays Kristján Leósson (Science Institute University of Iceland, Iceland) Hotel
La Residenza
We introduce a new technique of polarization analysis using arrays of metal nanoantennas. A properly designed nanoantenna array allows for full Stokes vector characterization of incident light in a transmission geometry. We describe the polarimeter design and show experimentally that results of polarization measurements are comparable to those performed with a commercial terminating rotating-waveplate polarimeter, but offer much faster response and minimal signal perturbation.

14:30>15:00 A relation between Second Harmonic Generation (SHG) and superchiral light in chiral plasmonic nanostructures
Ventsislav Valev (University of Bath, UK) Hotel
La Residenza
Due to the favorable power-law scaling of near-field enhancements, the nonlinear optical properties of chiral plasmonic nano- and metamaterials are of prime fundamental and practical interest. The chiroptical effects in SHG are typically three orders of magnitude larger than their linear optical counterparts. We report that nonlinear chiroptical effects are also sensitive to superchiral light enhancements.
17:10>17:40 Teleportation Scheme Based on Classical Entanglement Fabio Bovino (Selex-ES S.p.A., Italy)
Hotel La Residenza
Entanglement has always been a key issue in the foundation and interpretation of Quantum Mechanics. Classical Entanglement denotes the occurrence of some mathematical and physical aspects of quantum entanglement in classical beams of light. Here we extend the concept of classical entanglement to propose a novel architecture to implement quantum processor athat provides deterministic universal logic gate and more complex scheme as entanglement generator and teleportation.

Ab orientation onto AuNPs:
towards improved sensing performance
Maria Moros, Ana Claro and Jesus Martinez de La Fuente
Latest advances in the fields of microelectronics and nanotechnology have been critical towards the rapid
development of enhanced sensing platforms. Among the different
nanomaterials, gold nanoparticles (AuNPs) exhibit new optical properties that can be exploded to build new biosensors. For instance, plasmonic NPs can produce heat upon excitation of their plasmonic band with light, which can be used to develop immunosensors. In order to improve the biosensor performance, herein we report a two-step methodology which involves an initial rapid ionic adsorption of the Ab followed by a much slower Ab covalent attachment, resulting in a covalently attachment of the Ab in an oriented fashion. The used of the proposed thermo sensor is being applied for the identification at point-of-care of the nature of binders from micro-samples of artworks.

The recognition strategy promises to extend its application in studying the interaction between ligands and their cell-surface receptors.
