摘要

本文提出了一种基于偏压调制的双环谐波锁模光电振荡器仿真模型.该模型包括了利用电光调制器偏压调制实现的模式锁定、采用微波信号与滤波器冲激响应卷积实现的模式选择，以及基于双环信号相干叠加的超模噪声抑制.采用改进的脉冲跟踪法实现了双环信号的同步演化仿真.基于提出的模型仿真了谐波锁模状态下的输出微波脉冲信号的波形、频谱、超模噪声抑制和相位噪声特性，仿真结果与实验结果相符.该仿真模型可用于设计基于偏压调制的双环谐波锁模光电振荡器，以及研究双环腔内的动力学过程，有助于获得高超模噪声抑制比的微波信号.

Abstract

A simulation model is proposed for a harmonically mode-locked optoelectronic oscillator(OEO) based on a dual-loop architecture and bias modulation. The model includes bias modulation of the electro-optic modulator for mode locking

convolution of microwave signals and filter impulse response for mode selection

and time-domain interference of signals in two cavities for super-mode noise suppression. Numerical simulation is carried out based on the improved pulse tracking method to realize synchronous pulse evolution in two cavities. Through using this model

the waveform

the electrical spectra

the super-mode noise suppression and the phase noise characteristics of the generated microwave pulse trains under harmonic mode locking are numerically simulated

where the simulation results fit in with the experimental results. The proposed model can be used to design a harmonically mode-locked OEO based on a dual-loop architecture and bias modulation

and study the dynamic process in the dual-loop cavity

which is conducive to achieve microwave signals with super-mode noise suppression ratio.
