Abstract

We presented the self-planar mesa structure for improving the performances of 850-nm oxide-confined vertical cavity surface emitting lasers (VCSELs). Thermal simulation results demonstrated that the enhanced lateral heat dissipation and decreased series resistance within VCSELs could be gained using the self-planar mesa structure. By employing the selfplanar mesa, the maximum output power was increased from 8mW to more than 11mW, and the maximum wall-plug efficiency was improved from 26% to 36% for the VCSEL with an oxide aperture size of 13 μm at 15°C.
