基于XPM和ED-NALM光脉冲压缩的方案研究
Study on schemes for optical pulse compression based on XPM and Er-doped NALM
摘要
文章利用脉冲对的交叉相位调制(XPM)效应和非线性掺铒光纤放大环镜(ED -NALM)的整形放大作用，提出了一种对无啁啾高斯脉冲进行脉冲压缩的设计方案。数值模拟的结果表明，利用此方案可将脉宽为10 ps、中心波长为1 553 nm的无啁啾高斯脉冲压缩成脉宽为150 fs的无基座超短脉冲，且脉冲得到了很好的放大。
Abstract
On the basis of Cross-Phase Modulation (XPM) and Er-doped fiber Nonlinear Amplifying Loop Mirror (NALM), a novel design scheme is presented for the compression of unchirped Gaussian pulses with low peak power. The numerical simulations reveal that by using this scheme an unchirped optical pulse with 10 ps FWHM can be compressed to an ultra-short pedestal-free and well-amplified pulse with 150 fs FWHM.
