| 摘 要： | 利用状态空间法通过对含噪声项的Ｌａｎｇｅｖｉｎ速率方程的求解，得到半导体激光器开启瞬态光子数噪声的方差及其自相关函数．结果显示，半导体激光器非稳态的光子数噪声主要表现为弛豫振荡的颤抖时间．

| Abstract: | The approximate solution of rate equation with Langevin noise sources is described by state-space method. The variance and the autocorrelation function of the photon number noise for the turn-on transients are drawn out. It is shown that a significant part of the nonstationary photon number fluctuation can be described as timing jitter of relaxation oscillations. |
