ABSTRACT Inverse four-wave mixing (IFWM) is a nonlinear self-action effect also known as self-parametric amplification (SPA) which manifests itself as narrowing the optical spectrum of the pump wave propagating along the optical fibre. This paper aims to accurately model the IFWM process in various optical fibres including large effective-area fibre (LEAF) and highly nonlinear fibre (HNLF). Here, the coupled amplitude equations for the IFWM are derived based on the relative phase difference of interacting waves and impacts of the initial phase difference, pump and fibre parameters on the gain spectrum of the IFWM are examined. Results show that the maximum gain is obtained when the initial phase difference of the input waves set at and by increasing the initial phase to the gain is decreased to its minimum.

光纤中的相敏逆四波混频

摘要 反向四波混频 (IFWM) 是一种非线性自作用效应,也称为自参数放大 (SPA),其表现为使沿光纤传播的泵浦波的光谱变窄。本文旨在准确模拟各种光纤中的 IFWM 过程,包括大有效面积光纤 (LEAF) 和高度非线性光纤 (HNLF)。在这里,IFWM 的耦合幅度方程是基于相互作用波的相对相位差推导出来的,并检查了初始相位差、泵浦和光纤参数对 IFWM 增益谱的影响。结果表明,当输入波的初始相位差设置为 并通过增加初始相位到增益减小到其最小值时,获得最大增益。
