Abstract :
We report on planar proton implanted vertical-cavity surface-emitting laser diodes (VCSELs) with high output powers and high wall plug efficiencies for top surface emission. For optimized mirror reflectivities and proper mode alignment with respect to the gain spectrum a maximum cw output power of 15.5 mW and power conversion efficencies of 17.6 % are achieved for not heat sinked devices.
