摘要

本文讨论了引入无源区(可饱和吸收器)对阈值圆模产生的影响。提出了考虑空间孔燃烧和集成外耦反射影响的圆光栅表面发射激光器阈值工作的理论模型。建立了基于矢量波自洽非线性耦合模方程的半经典模型。通过对激光器特性的分析，得出了饱和吸收体不仅能产生方位模式识别，还能产生双稳态工作的结论。

Above threshold analysis of mode discrimination in circular grating surface-emitting lasers with saturable absorber

In this paper, the influence of introducing of passive region (saturable absorber) on threshold circular mode generation was discussed. The theoretical model of threshold operation of the circular grating surface-emitting (CG-SEL) laser taking into account effect of spatial hole burning and reflection from integrated outcoupler was proposed. A semiclassical model based on vector-wave self-consistent nonlinear coupled-mode equations was developed. Analysis of laser characteristics leads us to conclusion that the introduced saturable absorber causes azimutal mode discrimination and also bistable operation.
