Abstract

PURPOSE: To obtain a stable single horizontal oscillation mode and strong laser light even in case of low current density by constituting current throttling stripes formed inside a semiconductor laser device in the shape that the thin part from one flank toward the other flank in an expansion direction, part whose width increases gradually, and thick parts are arranged in order.
