Abstract:
1. A surface emitting laser device including an optical sensor, the device comprising: a surface emitting laser formed on a substrate and generating a laser beam; an optical sensor formed adjacent to the surface emitting laser on the substrate and receiving external light; and an absorbent layer formed on a side surface of the surface emitting laser adjacent to the optical sensor, wherein the surface emitting laser is formed to have a predetermined structure in which a first reflector, a first cladding layer, an active layer, a second cladding layer, and a second reflector are stacked in sequence on a semiconductor layer, and the optical sensor is adjacent to the surface emitting laser on the substrate and formed to have a predetermined structure in which a part of the semiconductor layer and the first reflector are exposed, the laser beam generated on the surface emitting laser and the external light received on the optical sensor are different in wavelength.
