Semiconductor device with angle reflector

摘要

The device has a semiconductor laser chip formed as a pumping radiation source and an edge emitter. The chip has an active layer for emitting electromagnetic radiations. An angular reflector (1) is arranged in the chip for forming a resonator (10) for the radiations emitted by the layer. The reflector has two reflective surfaces (14, 15) arranged at an angle between 70 and 90 degrees to each other. The radiations impinge at the surface (14) as incident radiations (3), and are reflected from the surface (14) to the surface (15).
