对半导体光放大器中基于光双稳性的随机共振进行了数值研究，以提取埋在噪声中的微弱脉冲信号。分析了不同系统参数下光双稳性的输出特性，它决定了随机共振的性能。通过对这些参数的优化，通过随机共振提取噪声隐藏信号，获得最大的大于9的互相关增益。这为各种信号处理领域中微弱光信号的检测提供了一种新的技术。
The stochastic resonance based on optical bistability in the semiconductor optical amplifier is numerically investigated to extract a weak pulse signal buried in noise. The output property of optical bistability under different system parameters is analyzed, which determines the performance of the stochastic resonance. Through optimizing these parameters, the noise-hidden signal is extracted via stochastic resonance, in which the maximum cross-correlation gain higher than nine is obtained. This provides a novel technology for detecting a weak optical signal in various signal processing fields.
