  • OPTOELECTRONIC COMPONENT, SEMICONDUCTOR STRUCTURE AND METHOD
    Publication number: 20220376134
    Abstract: A semiconductor structure comprises an n-doped first layer, a p-doped second layer doped with a first dopant, and an active layer disposed between the n-doped first layer and the p-doped second layer and having at least one quantum well. The active layer of the semiconductor structure is divided into a plurality of first optically active regions, at least one second region, and at least one third region. Here, the plurality of first optically active regions are arranged in a hexagonal pattern spaced apart from each other. The at least one quantum well in the active region comprises a larger band gap in the at least one second region than in the plurality of first optically active regions and the at least one third region, the band gap being modified, in particular, by quantum well intermixing. The at least one second region encloses the plurality of first optically active regions.
