互注入锁定产生波长可调谐光脉冲的实验研究

Wavelength tunable optical short pulse generation by mutual pulse injection seeding scheme

本文提出了一种利用两个F -P半导体激光器双向注入锁定产生波长可调谐光脉冲的实验系统。该实验系统只需调节可调谐滤波器就可以方便地选择不同波长的单纵模光脉冲,在2 5nm的波长调谐范围内边模抑制比(SMSR)为2 6dB ,其中18nm的波长范围内高于3 1dB。

A simple and robust system is presented to generate electrically wavelength tunable optical short pulses by the use of two gain-switched Fabry-Perot laser diodes in a mutual pulse injection seeding scheme.The operating wavelength of the optical pulses is flexibly selected by adjusting a tunable filter.The side mode suppression ratio achieved by the system is larger than 26 dB over the wavelength region of 25nm and higher than 31dB within 18nm wavelength range.
