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.
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.
