摘要

最近，我们成功地利用具有小的正常群速度色散(GVD)[1]的色散平坦光纤，产生了宽度大于200nm的超连续光谱(SC)。由于这种SC脉冲在整个脉冲宽度上具有线性上啁啾，我们可以通过使用适量的异常GVD将脉冲宽度压缩到其傅里叶变换限制(TL)值。

Generation of 200-fs Fourier-Transform-Limited Optical Pulses at 1550 nm from Super-Continuum Obtained by a Mode-Locked Semiconductor Laser

Recently, we have succeeded in generating the very flat super-continuum (SC) spectrum wider than 200 nm centered at 1550 nm by using a dispersion-flattened fiber having a small normal group-velocity dispersion (GVD) [1]. Since such SC pulse has linear up-chirp across the entire pulse width, we may compress the pulse width to its Fourier-transform-limited (TL) value by using an appropriate amount of anomalous GVD.
