The paper presents the results of the experimental study of an application of the phenomenon of vibrational resonance (VR) for enhancement of the response of a bistable vertical-cavity surface-emitting laser (VCSEL) to the effect of optical modulating signals. Specifically, two different cases were investigated: (a) the control of all-optical switching caused by a modulated orthogonal optical injection from another VCSEL and (b) the amplification of autodyne signals from a vibrating diffusely reflecting surface in the self-mixing optical interferometry. It is experimentally demonstrated that an application of the phenomenon of VR in both cases studied leads to a strong amplification of the input optical signals by a factor from 10 to 200 depending on the experimental conditions with respect to the initial values. The effect of the asymmetry of a bistable potential on the amplification factor was also studied. The results obtained can be used to improve all-optical switchings for application in communication systems and enhancement of autodyne signals in self-mixing optical interferometry. This article is part of the theme issue ‘Vibrational and stochastic resonance in driven nonlinear systems (part 1)’.

双稳态垂直腔面发射激光器的振动共振放大光信号

本文介绍了应用振动共振 (VR) 现象来增强双稳态垂直腔面发射激光器 (VCSEL) 对光调制信号影响的响应的实验研究结果。具体而言，研究了两种不同的情况：（a）由来自另一个 VCSEL 的调制正交光注入引起的全光切换的控制和（b）自混合光学干涉测量中来自振动漫反射表面的自达信号的放大. 实验证明，在所研究的两种情况下，VR 现象的应用都会导致输入光信号的放大倍数为 10 到 200，这取决于相对于初始值的实验条件。还研究了双稳态电位的不对称性对放大系数的影响。获得的结果可用于改进通信系统中应用的全光开关和自混合光学干涉测量中自达信号的增强。本文是主题问题“驱动非线性系统中的振动和随机共振（第 1 部分）”的一部分。
