摘要

采用线性近似法计算了单模激光损失模型在输入偏置信号的调幅波时的光强关联函数C(t).发现光强关联函数C(t)随时间t的演化存在多种变化形式(不规则周期递增、递减等多种振荡形式).结果表明: 当a0=0.1时, 出现平坦的不规则周期性振荡; 低频调制信号频率Ω可调整不规则周期振荡的周期; 量子噪音强度Q和高频载波信号频率ω能改变曲线C(t)的初始值和周期.

Abstract

By using the linear approximation method, the intensity correlation function C(t) of loss model laser system with a biased amplitude modulation was calculated. The different forms (irregularly periodic increasing, decreasing and so on) were obtained in the evolution of the intensity correlation function C(t) with the time t. The results indicate that: in the case of a0=0.1, the flat irregularly periodic oscillation is shown; the period of irregularly periodic oscillation is adjusted by the low frequency Ω of modulation signal; the initial value and the period of C(t) can be changed by the intensity of quantum noise Q and the high frequency ω of carrier signal.
