ABSTRACT:
An optical semiconductor device includes a distributed Bragg reflection layer of a first conductivity type, a distortion elaxation layer of the first conductivity type, a light absorbing layer, and a semiconductor layer of a second conductivity type, sequentially arranged on a semiconductor substrate. The distortion relaxation layer the same material as the semiconductor substrate. The total optical length of layers between the distributed Bragg reflection layer and the light absorbing layer is an integer multiple of one-half the wavelength of incident light that is detected.
