通过一个光相位调制器的实例，介绍利用Optisystem 中Matlab Component组件联合M atlab实现用户自定义光学组件的方法。对相位调制基本原理、相位调制器理论模型和实现模型的Matlab代码进行分析，介绍如何将用户自定义器件功能代码关联Matlab Component组件进行仿真，并利用自定义的相位调制器对理论分析进行验证。(Through an example of an optical phase modulator, this paper introduces the

通过伪随机序列进行频率调制，并对相位连续性进行优化。调制信号的自相关函数可以通过谱修正进行旁瓣抑制(Frequency modulation is performed by pseudo-random sequence and phase continuity is optimized. The autocorrelation function of modulation signals can be sidelobe suppressed by spectral correction)
