摘　　要：用线性化近似方法,计算了具有色关联的色抽运噪声和色量子噪声驱动的光学双稳系统的光强相对涨落,讨论了噪声间的关联和输入信号对光强相对涨落的影响,发现光强相对涨落随抽运噪声强度和量子噪声强度的变化过程中存在极小值,且光强相对涨落与噪声间的关联程度密切相关,但输入信号对其影响不大.Using the linear approximation method, the intensity fluctuation of the optical bistable system driven by both the colored pump noise and colored quantum noise with cross-correlation was calculated and the influence of intensity of noise and its cross-correlation form on intensity fluctuation was discussed It＇s found that there is a minimum of the intensity fluctuation when the intensity of the pump noise and the quantum noise change, and it is closely related to the cross-correlation of the noises, but the input signal has little effect on the intensity fluctuation
