面发射半导体激光器的研制进展

Developing Progress of Surface Emitting Semiconductor Lasers

随着高速大容量光信息处理技术发展需求的增长,二维(2D)阵列型光发射器件变得日益迫切。为了实现2D阵列激光器,发射光垂直于衬底的表面发射激光器(SEL)成为关键器件。本文综述了某些重要的面发射激光器及其阵列的结构和激射特性。三种基本结构——光栅耦合型、45°偏转镜面型和垂直腔型SEL竞相成为最佳的器件结构。文中还讨论了2D阵列激光器的应用前景。

As the demand for high speed and large capacity optical information processing increases,two-dimensionally(2D) arrayed light-emitting devices have come to be more and more necessary. For realizing two-dimensionally arrayed lasers,surface emitting lasers(SEL) which emit light vertical to the substract are becoming crucial. Some structures and lasing characteristics of SEL and 2D arrayed devices are summerized in this paper Three basic structures--grating coupled,45°deflector and vertical cavity SEL are vying for preeminence as SEL. The applications of 2D arrayed lasers are also discussed.
