Abstract

Transverse dynamics of a broad-area semiconductor surface-emitting laser with a vertical resonator (VCSEL) with еxternal optical injection was investigated above threshold. It is obtained that two types of instabilities can develop in system: Turing and Hopf instabilities. Turing instability in turn can be subdivided into plane-wave instability (PWI) and modulation instability (MI). We found some sets of system parameters where the steady-state curve of the homogeneous solution can be bistable or monostable. Modulation instability can lead to the development of spatial patterns, which was obtained.

阈值以上驱动VCSEL的调制不稳定性

在阈值以上研究了具有垂直谐振腔的宽面积半导体表面发射激光器（VCSEL）的横向动力学。得到了系统中可发展的两类不稳定性：图灵不稳定性和霍普夫不稳定性。图灵不稳定性又可以细分为平面波不稳定性（PWI）和调制不稳定性（MI）。我们发现了一些系统参数集，其中齐次解的稳态曲线可以是双稳态的或单稳态的。调制的不稳定性可以导致空间模式的发展，这是已经获得的。

期刊介绍： The journal covers a wide range of issues in information optics such as optical memory, mechanisms for optical data recording and processing, photosensitive materials, optical, optoelectronic and holographic nanostructures, and many other related topics. Papers on memory systems using holographic and biological structures and concepts of brain operation are also included. The journal pays particular attention to research in the field of neural net systems that may lead to a new generation of computional technologies by endowing them with intelligence.
