Chapter 5 Conclusions
The high-speed and short pulse laser source has attracted a lot of attention all over the word. In communication system, the high bit rate is very important image transmission in future. The active mode-locked laser is the most efficient method to generate high data rate and ultrashort pulse.
In chapter 2, we have demonstrated a new structure of using amplitude modulated and SOA in fiber ring laser. We have trigger the mode locked laser of repetition rate of 5Gb/s, 10Gb/s, 15Gb/s, 25Gb/s, 30Gb/s, , 40Gb/s with modulation frequency of 2.49788842GHz, 2.48766343GHz, 49728146GHz, 2.49665541GHz, 2.49122333GHz, 2.48811346GHz. In the above experiment, we have known repetition rate and RMS jitter changing with modulation.
In chapter 3, we have demonstrated an structure of using phase modulated fiber ring laser. We have trigger the mode locked laser of repetition rate of 5Gb/s, 10Gb/s, 20Gb/s, 50Gb/s with modulation frequency of 2.49788842 GHz, 2.48766343GHZ, 2.49728146 GHz,

2.49728146 GHz. In the above experiment, we have known repetition rate, RMS jitter and rise time changing with modulation.
In chapter 4, we have demonstrated a new structure of using amplitude modulated fiber ring laser. We have trigger the mode locked laser of repetition rate of 5Gb/s, 7.5Gb/s,10Gb/s, 20Gb/s with modulation frequency of 2.62334676 GHz, 2.66331431 GHz, 2.6423582 GHz, 2.65734218 GHz. In above experiment, we have known repetition rate ,RMS jitter and rise time changing with modulation.
