Conclusion

Through the simulation and analysis of 1x(2N+1) MMI optical splitters based on sol gel glass waveguide with computer-aided BPM software mentioned in Chapter 2, the conclusions are given in following texts. We examine their properties for application in integrated optics, the different length, width, height, and wavelength relation of 1x(2N+1) MMI optical splitters based on sol gel glass waveguide are analyzed, compared and designed. The relations of length, width, wavelength response, depth in 1x(2N+1) optical power splitters based on sol gel waveguide can be discussed.

In Chapter 3, we simulate the OTDM transmission system based on the 1x(2N+1) optical splitter we designed. And we achieve the OTDM transmission system by using the different length of fiber to generate 40Gbit/s, 50Gbit/s, 80Gbit/s, 100Gbit/s optical pulse train. Besides we also analyze each the bit error rate of output port of 1x(2N+1) optical splitter.

According to the study in Chapter 2, we extend to fabricate 1x(2N+1)

MMI power splitters based on sol gel glass on quartz in Chapter 4. The

preparation of sol gel glass solution also described. The absorption spectral and refractive index of sol gel thin film are presented in this section. And the OM will display the manufacture result of 1x3, 1x5, 1x7 optical power splitters and channel waveguide in this section. According to simulation results of our designed sol gel power splitter, we can apply those optical devices as key component in optical communication systems.

Finally, the final purpose of our design devices is working to face the

optical time division multiplexer optical system.
