Abstract
An integrated tapered diode laser arrangement comprises an injector region () and a region () which is optically coupled to the injector region and expands in a cross section. At least one of said regions () has a quantum well structure with a plurality of semiconductor materials, wherein the semiconductor materials are intermixed at least in one region (). The intermixed region () has a larger electrical band gap than a non-intermixed region.
