利用DCF,DSF和ED-NALM获得无基座超短光脉冲的设计方案
A designed model for pedestal-free ultra-short pulse generation using DCF,DSF and ED-NALM
【摘要】 提出了一种利用色散补偿光纤(DCF)、色散位移光纤(DSF)和非线性掺铒光纤放大环镜(EDNALM)对增益开关分布反馈(GSDFB)半导体激光器产生的啁啾光脉冲进行压缩的方案。数值模拟的结果表明,利用此方案可将GSDFB半导体激光器产生的脉冲宽度(半极大全宽度)为30ps的啁啾光脉冲压缩为180fs的无基座超短脉冲。
【Abstract】 Based on the dispersion-compensation fiber (DCF),the dispersion-shift fiber (DSF) and erbium-doped nonlinear amplifying fiber loop mirror (ED-NALM),a novel designed model of the optical pulse compression to t he chirped pulse generated from gain-switched distributed feedback (GS-DFB) se miconductor laser was presented.The numerical simulations reveal that a chirped optical pulse with 30ps full-width in half maximum generated from GS-DFB semic onductor laser can be compressed to a pedestal-free pulse with 180fs full-widt h.
