Highly efficient operation of curved mirror VCSELs and their uniform characteristics

Abstract

Highly uniform and efficient GaN-based VCSELs with curved mirrors were obtained from a single wafer. The average Ith was 0.64 mA with standard deviations of 0.043 mA. The peak WPE and output power were 13.4 % and 7.6 mW at 5.2 mA and 12.8mA operating current, respectively.
