Abstract

We report a numerical investigation of how the dispersion slope affects the soliton spectral tunneling (SST) in a photonic crystal fiber with three zero dispersion wavelengths. It is discovered that a larger dispersion slope makes group-velocity mismatch between the initial soliton and the transferred wave thereby suppressing the SST effect, while a proper decrease of the dispersion slope enhances the SST effect to widen a supercontinuum range. Besides, we find a soliton-like leaking dispersion wave, which can sustain information and energy for a short time within a particular spectral range.

色散斜率对光子晶体光纤孤子光谱隧穿的影响

本文报道了色散斜率对具有三个零色散波长的光子晶体光纤中孤子光谱隧穿(SST)的影响。发现较大的色散斜率会使初始孤子与传递波之间的群速度不匹配，从而抑制海温效应，而适当减小色散斜率会增强海温效应，从而扩大超连续谱范围。此外，我们还发现了一种类似孤子的泄漏色散波，它可以在特定的光谱范围内短时间维持信息和能量。
