摘要

本文描述了一种结合了GaAs镜面和InP有源层优点的混合方法，用于InP/GaAs晶圆键合1.31 /spl mu/m VCSELs。这种新颖的器件概念具有腔内环接触，五个应变补偿AlGaInAs量子阱和AlInAs/InP隧道结，以减少p掺杂层的吸收。隧道结实际上被限制形成一个孔径，用于电流注入和导波。采用自洽式VCSEL仿真软件对器件内部物理特性进行分析和优化。

Balanced optimization of 1.31 /spl mu/m tunnel-junction VCSELs

A hybrid approach that combines the advantages of GaAs mirrors and InP active layers in InP/GaAs wafer bonded 1.31 /spl mu/m VCSELs is described. This novel device concept features intra-cavity ring contacts, five strain-compensated AlGaInAs quantum wells, and an AlInAs/InP tunnel junction in order to reduce absorption by p-doped layers. The tunnel junction is literally confined forming an aperture for current injection and wave guiding. A self-consistent VCSEL simulation software is employed in order to analyze and optimize the internal device physics.
