Abstract:
A three-dimensional waveguiding structure for a microcavity surface-emitting laser in which native aluminum oxide layers provide control of intracavity waveguiding and the laser optical mode structure of the emitted beam, said waveguiding structure comprising:(a) a substrate;(b) a first distributed Bragg reflector mirror deposited on said substrate;(c) a quarter wave p+ GaAs first contact layer deposited on said first Bragg reflector mirror;(d) a half wave optical cavity deposited on said first contact layer, said cavity including a central layer of In.sub.0.2 Ga.sub.0.8 As defining a gain region and a GaAs layer, an Al.sub.0.67 Ga.sub.0.33 As layer, an Al.sub.0.97 Ga.sub.0.03 As aperture layer and an Al.sub.0.9 Ga.sub.0.1 As layer on each surface of said central layer;(e) a quarter wave n+ GaAs second contact layer deposited on said cavity; and(f) a second distributed Bragg reflector mirror deposited on said second contact layer.
