摘要

摘要我们在这项工作中报告了对绝缘体硅波导内的艾里脉冲产生的超连续现象的数值研究，包括损耗效应、三次谐波产生（THG）和负频率克尔（NFK）项。这项研究是通过基于全单向脉冲传播方程模型的建模进行的，该模型允许假设在具有频谱滤波的克尔非线性中存在 NFK 项。研究探讨了线性损耗、自由载波吸收/自由载波色散、双光子吸收、THG、NFK、峰值功率、脉冲持续时间和脉冲形状的各种影响。

Supercontinuum generation of Airy pulses in a silicon-on-insulator optical waveguide including third-harmonic generation and negative-frequency Kerr terms

We report in this work the numerical study of the supercontinuum phenomenon raised from Airy pulses within a silicon-on-insulator waveguide including loss effects, third-harmonic generation (THG) and negative-frequency Kerr (NFK) terms. This study is conducted through a modeling based on the full unidirectional pulse propagation equation model which allows to assume the existence of the NFK term in the Kerr nonlinearity with a spectral filtering. The various effects of the linear loss, the free-carrier absorption/ free-carrier dispersion, the two-photon absorption, the THG, the NFK, the peak power, the pulse duration and the pulse shape are explored.
