ABSTRACT:
A semiconductor laser device has a high switching speed and low cost, and comprises a common electrode, on the surface of a P-type semiconductor wafer forming plural light sources. The semiconductor laser device is further featured by having grooves provided on said semiconductor wafer to allow independent drive of said light sources and to reduce the distance between the light-emitting points of the light sources.
