Abstract
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.
