Abstract

High power operation of circular-grating surface-emitting distributed Bragg reflector lasers is demonstrated. The structure is a strained InGaAs/GaAs double quantum well grown by one step MBE. Circular gratings are defined by electron beam lithography. A surface emission power over lOOmW is obtained.
