An all-optical spike inhibition scheme based on polarization-mode competition (PMC) in a vertical-cavity surface-emitting laser (VCSEL) with an embedded saturable absorber is proposed and investigated numerically. The inhibitory dynamics is characterized by spike amplitude and first-spike latency (FSL) for the first time, to the best of our knowledge. The effects of time differences between inhibitory and excitatory inputs, inputs strengths, bias current, as well as noise on the spike amplitude and FSL are examined. The results show that a spike can be triggered in the y-polarization mode by excitatory input and can be inhibited in the presence of inhibitory input due to PMC.
提出并数值研究了一种基于嵌入可饱和吸收体的垂直腔面发射激光器（VCSEL）中偏振模式竞争（PMC）的全光尖峰抑制方案。据我们所知，首次用尖峰幅度和首次尖峰潜伏期（FSL）来描述抑制动力学。研究了抑制和兴奋输入之间的时间差、输入强度、偏置电流以及噪声对尖峰幅度和 FSL 的影响。结果表明，由于 PMC，在 y 偏振模式下，通过兴奋输入可以触发尖峰，而在存在抑制输入的情况下可以抑制尖峰。
