Abstract

PURPOSE: To obtain a laser which is easy to control lateral mode and is simple to produce is obtained by covering the regions including a PN junction near the active layers exposed on both side faces of mesa stripe with a polycrystal or amorphous substance of a refractive index smaller than the active layer crystal.
