Abstract
Fabrication of a high-quality Fabry-Perot resonator with a GaAs active layer and two Bragg AlAs/(AlAs)2(GaAs)9 reflectors is reported. This structure lases CW at room temperature when photopumped. Mirror reflectivity of 97%, threshold pump power of 16 mW, and quantum efficiencies up to 7% are demonstrated.Keywords
