摘　　要：本文利用光纤光栅形成外腔反馈 ,得到量子阱半导体激光二极管单模超短光脉冲 .其光谱线宽约为 0 .4nm,脉冲宽度约为 60 ps.并利用调谐装置 ,改变光纤光栅的反射波长 ,得到不同波长的超短光脉冲 ,其波长可长期稳定 .In this paper we report the generation of single mode pulse trains from a quantum well laser diode (QWLD) by using a fiber Bragg grating.The optical spectral width is about 0.4nm,while pulse width is 60ps.In addition,we can get super short pulse with different frequencies by using a fiber Bragg gratings tuning technique,while their wavelengths are stable.
