Semiconductor laser including phototransistor |
| abstract |
The present invention relates to a semiconductor laser for use in an optical module for measuring distance and / or motion using magnetic mixing effects. The semiconductor laser comprises a layer structure comprising an active region 3 interposed between two layer sequences 1 and 2 and further comprises a light detector arranged to measure the intensity of the resonant light field in the laser. . The photo detector is a photo transistor consisting of an emitter layer (e), a collector layer (c) and a base layer (b), each of which is a bulk layer and forms part of one of the layer sequences (1, 2) do. With regard to the proposed semiconductor laser, the optical module based on this laser can be manufactured more easily at low cost and small size than the known modules. |
