Abstract
An InGaAs-GaAs-AlGaAs strained layer single quantum laser array with a reactive ion etched corner reflector array as its rear facet has been fabricated. The corner reflectors play a two-fold role as a highly re flective rear mirror and as a phase-locking coupler. Phase locked oper ation with beam widths as low as 0.64-degrees are obtained at pumping currents up to 4xI(th) and output powers up to 60 mW. The coupling mec hanism and the benefit of the corner reflector to output performance a re discussed.
