Abstract

Abstract Translated from German Halbleiterlaseranordnung mit einem Laserbereich (A), in dem zur Wellenführung ein Wellenleiter (4) vorgesehen ist, der so bemessen ist, daß die Laserstrahlung senkrecht zu ihrer Ausbreitungsrichtung im Grundmodus schwingt, mit einem Koppelbereich (B) und mit einem Verstärkungsbereich (C), in dem die laterale Wellenführung aufgehoben ist und der mit einem Kontakt zur Strominjektion versehen ist. Semiconductor laser arrangement with a laser region (A), in which a waveguide (4) is provided for the waveguide, which is dimensioned such that the laser radiation oscillates perpendicular to its direction of propagation in the basic mode, with a coupling region (B) and with an amplification region (C), in which the lateral wave guide is canceled and which is provided with a contact for current injection.
