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.
The linear correlation method was used to calculate the light intensity correlation function C (t) of the single-mode laser loss model when the amplitude-modulated wave was input to the bias signal. It was found that the evolution of the light intensity correlation function C (t) The results show that when a0 = 0.1, flat irregular periodic oscillation occurs; the frequency of low frequency modulation signal can adjust the period of irregular periodic oscillation; the quantum noise intensity Q and The high frequency carrier signal frequency ω can change the initial value and period of the curve C (t).
