Abstract

Strategies for power scaling VECSELs, including improving thermal management, increasing the quantum well gain/micro-cavity detuning that increases the threshold but increases roll-over temperature, and double-passing the excess pump via reflection from a metalized reflector at the back of a transparent distributed Bragg reflector (DBR) were studied. The influence of the heat spreader thickness and the pump profile on the temperature rise inside the active region was investigated using commercial finite element analysis software. Improvement was observed in optical efficiency of the VECSEL devices with a transparent DBR by double passing the pump light. Higher dissipated power at maximum output power was found in devices with larger spectral detuning between the quantum well gain and the micro-cavity detuning.
