| titleOfInvention | Surface type semiconductor light switch |
| abstract | PURPOSE: To obtain a surface type semiconductor light switch which operates with low switching energy and produces a high light output with high speed response by a method wherein a hetero junction bipolar photo transistor for receiving an incident light and a surface emitting laser for outputting a laser light are so formed as to be laminated in series on a same substrate. n CONSTITUTION: In 2 mirror portions constituting a resonator of a surface light- emitting laser, 2 types of semiconductor AlAs/Al 0.05 Ga 0.95 As having different refractive indexes and in which the thickness of each layer is odd times of 1/4 of laser resonant wave length are laminated to provide a distribution brag reflection type mirror (DBR). Here, a p + -Al 0.2 Ga 0.8 As clad layer 13, an n + -Al 0.9 Ga 0.7 As clad layer 15 and a p + -Al 0.1 Ga 0.9 As ohmic layer 11 are provided. Then, a laser light released to the side of a hetero junction bipolar light transistor is absorbed into a p-In 0.05 Ga 0.95 As base layer 18. Further, an incident light is reflected on a DBR mirror to be absorbed while it passes through the base layer 18 twice. n COPYRIGHT: (C)1992,JPO&Japio |
