10GHz Gain-Switched DFB Laser with Low Timing Jitter |
| |
| Abstract: | The gain-switched DFB pulse source has been obtained at 10GHz repetition rate with the DFB laser diode chips that are made in China.The optical timing jitter is reduced to 840fs by using the self-seeding injection based on a simple structure.The self-injection seeding sensitivity to the variations in temperature and modulating frequency has been measured.The 5ps Predestal-free Pulas Generation is achieved utilizing normal dispersion compensation and a Comb-like Dispersion Profiled Fiber Compressor. |
