Abstract
Data are presented demonstrating improved laser operation of AlxGa1-xA s-GaAs-InyGa1-yAs quantum well heterostructures modified with buried n ative oxide current-blocking windows. The windows are formed by low te mperature (425-degrees-C) anisotropic ''wet'' oxidation of an Al0.9Ga0 .1As layer exposed at the facets of metallized laser bars. These windo w devices operate continuously to powers as high as 248 mW/facet (unco ated, approximately 10.5 mum aperture), a apoproximately 25% improveme nt over nonwindow devices.
