ABSTRACT:
Provided are a surface emitting laser device having an optical sensor, and an optical waveguide device employing the same. The surface emitting laser device having an optical sensor includes a surface emitting laser formed on a substrate and generating a laser beam to output it to outside, and an optical sensor formed adjacent to the surface emitting laser on the substrate and receiving external light. In the surface emitting laser device having the optical sensor, and the optical waveguide device employing the same, the surface emitting laser and the optical sensor are simultaneously integrated, however, the performance of the surface emitting laser is unaffected by the optical sensor and the optical sensor operates separately, exhibits high performance, and can respond within a wide wavelength band.
