摘要
基于光折变自弯曲相继四波混频多作用区理论,利用类电子学观点建立了多作用区互抽运相位共轭效应(MPPC)输出特性的理论计算模型。根据此模型数值模拟了作用区之间振幅传输系数对MPPC阈值耦合强度以及反射率的影响,发现振幅传输系数越低,MPPC所需要的阈值耦合强度越高,且在相同的耦合强度下,其输出反射率越低。实验研究了鸟翼式互抽运相位共轭器的输出特性,获得了器件反射率随入射位置变化的曲线,并建立了四作用区鸟翼式互抽运相位共轭器输出特性的理论模型,数值模拟与实验结果基本一致。
Based on the photorefractive self-bending successive four-wave mixing interaction theory, a computational model of mutually pumped phase conjugation （MPPC） with multiple coupled interaction regions is proposed to analyze the output characteristics under an electronics-like point of view on four-wave mixing. Using the model, the influence of threshold coupling strength and phase-conjugate reflectivity on transmissivity between the coupled interaction regions is investigated. The smaller transmissivity will decrease the phase-conjugate reflectivity under the same coupling constant and increase the threshold coupling constant. The output characteristics of bird wing MPPC are studied with experiment, and the dependence of phase-conjugate reflectivity of MPPC on the incident position is presented. An output characteristics model of bird wing MPPC with four coupled interaction regions is proposed, and simulation conclusions are in agreement with the experimental results.
