偏置信号调制下色关联噪声驱动的单模激光的光强相对涨落

采用线性化近似，计算了由具有色关联的受偏置信号调制的色泵噪声和色量子噪声驱动 的单模激光增益模型的光强相对涨落，发现相对涨落随噪声强度的变化曲线中存在极小值，分析了偏置信号的强度、周期信号频率、噪声间的互关联强度和互关联时间对曲线的影响； 对单模激光增益模型在偏置信号调制和直接信号调制两种方式下的输出光强相对涨落进行了比较，发现光强涨落与偏置信号的强度密切相关. 关键词： 偏置信号调制 光强相对涨落 线性化近似

Normalized intensity fluctuation for bias signal modulation in a single-mode laser driven by colored correlated noises

Using the linear approximation method, the normalized intensity fluctuation(NIF) for bias signal modulation is calculated in a gain-noise model of a single-mode laser driven by colored correlated noises, in which each is colored; and the influences of the strength of bias signal modulation, the frequency of period signal, the correlation strength and correlation time of noises on NIF is studied in detail. We observed that a minimum appears in the NIF versus pump noise intensity curve and quantum noise intensity curve; the normalized intensity fluctuations of a single-model laser for bias signal-modulation and direct signal modulation are compared.
