Abstract

The method of fabrication provides for the processing of an epitaxially grown convention planar laser structure, normally processed to produce a gain-guided laser, to provide an index-guided single stripe or rnultastripe laser which has better output beam properties for many applications, suck as optical disk recording and playback systems. The method comprises the employment of a low index material, e.g., Ti02 or GaN, in areas of a cladding layer of the laser adjacent to the region to be established for lasing operation.
