  • 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.

  • Semiconductor laser
    Patent number: 11495939
    Abstract: A semiconductor laser is provided that includes a semiconductor layer sequence and electrical contact surfaces. The semiconductor layer sequence includes a waveguide with an active zone. Furthermore, the semiconductor layer sequence includes a first and a second cladding layer, between which the waveguide is located. At least one oblique facet is formed on the semiconductor layer sequence, which has an angle of 45° to a resonator axis with a tolerance of at most 10°. This facet forms a reflection surface towards the first cladding layer for laser radiation generated during operation. A maximum thickness of the first cladding layer is between 0.5 M/n and 10 M/n at least in a radiation passage region, wherein n is the average refractive index of the first cladding layer and M is the vacuum wavelength of maximum intensity of the laser radiation.
