摘要: Disclosed is a semiconductor laser that is constituted by at least one active layer sandwiched between two confinement layers with P and N type doping to constitute a PN junction. In at least one of the confinement layers and/or the active layer, holes are designed on each side of the cavity so as to form structures of photonic bandgap material along the lateral walls of the cavity and the ends of the cavity.

摘要: A semiconductor chip is specified, comprising an active layer provided for emitting an electromagnetic radiation, and a two-dimensional arrangement of structural units, which is disposed downstream of the active layer in a main emission direction of the semiconductor chip. The structural units are arranged in an arbitrary statistical distribution. Such an arrangement of structural units makes it possible to realize a semiconductor chip having a directional emission characteristic.
