一种新的波长可调谐光脉冲的生成方案
A New Scheme of Wavelength Tunable Optical Short Pulse Generation
【摘要】 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方案,可生成双波长可调谐光脉冲.利用光纤光栅(FBGs)作为滤波元件,通过应力作用在两个光纤光栅上以改变它们的反射波长和适当调整可调谐光延迟线(VODL)长度,可得到不同波长的光脉冲输出,而重复频率保持524.6MHz不变.在13.2nm调谐范围内边模抑制比高于25dB,系统稳定且波长调节便利.
【Abstract】 :A mutual pulse injection-seeding scheme is developed to generate tunable dual-wavelength optical short pulses by useing two gain-switched Fabry-Pérot laser diodes. Wavelength selection and tuning are achieved by adjusting two fiber Bragg gratings and optical delay lines while a constant repetition frequency of 524.6 MHz can be maintained. The sidemode suppression ratio of the output pulses is better than 25 dB over a wavelength-tuning range of 13.2 nm. The system is robust and convenient for wavelength-tuning.
