Abstract

Es wird ein kantenemittierender Halbleiterlaser mit einem Halbleiterkörper (1), der einen Wellenleiterbereich (2) aufweist, angegeben. Der Wellenleiterbereich (2) weist eine untere Mantelschicht (3a), eine untere Wellenleiterschicht (4a), eine aktive Schicht (5) zur Erzeugung von Laserstrahlung, eine obere Wellenleiterschicht (4b) und eine obere Mantelschicht (3b) auf. Weiterhin weist der Wellenleiterbereich (2) mindestens einen strukturierten Bereich (6) zur Streuung der Laserstrahlung auf, in dem eine laterale Grundmode der Laserstrahlung geringere Streuverluste als die Strahlung höherer Lasermoden erfährt.
