英文摘要 | PURPOSE:To realize an optical integrated element, in which a semiconductor laser and a photodetector are brought near to each other and integrated onto the same substrate and which has high performance, by constituting a light- receiving surface in the photodetector in a plurality of the surfaces forming a Brewster angle to incident beams from the semiconductor laser. CONSTITUTION:A groove 5 in width of approximately 20mum is shaped to a semiconductor laser, and one of the semiconductor laser is operated as a semiconductor laser 2 and the other as a photodetector 3. The groove 5 is used as the reflecting surface of the semiconductor laser 2 formed vertically to the optical axis of the laser on the semiconductor laser 2 side at that time. The photodetector 3 side of the groove 5 is etched so as to shape a curve group. The reflectivity of the photodetector 3 reaches to zero, and incident beams from the semiconductor laser 2 can be absorbed into a crystal efficiently. Accordingly, a plurality of light-receiving surfaces are formed, thus shortening distances up to the light-receiving surfaces from a light-emitting surface, then improving coupling efficiency. |
