Title: Single-ended output GaAs/AlGaAs single quantum well laser with a dry-etched corner reflector

Abstract

GaAs/AlGaAs single quantum well lasers with integrated corner reflectors have been fabricated using chemically assisted ion beam etching. The air-GaAs interface is internally totally reflecting, and no coherent radiation is transmitted through the corner reflector. The corner reflector laser was compared with a conventional Fabry--Perot laser cleaved from the same wafer. An 11% reduction in threshold current and a reduction of the far-field angle from 4.4{degree} to 0.7{degree} was measured.
