ABSTRACT:
A semiconductor laser comprising a substrate; a current blocking layer formed on said substrate; a striped channel formed in said current blocking layer on said substrate, said striped channel being narrow in the vicinity of the facets and being wide inside of the facets; an active layer, a portion of the active layer corresponds to the narrow portion of said striped channel being a plane to form a window region and another portion of the active layer corresponds to the wide portion of said striped channel being a crescent shape to form a laser operation area with a mesa-structure which is surrounded by burying layers to cut off current leakage from said laser operation area, the width of the mesa-portion of said laser operation area being not less than that of a current injection region formed within said striped channel.
