Light receiving device |
摘要 |
A light absorbing layer, and a window layer formed thereon constitutes a first conduction-type semiconductor layer. In a part of this first conduction-type semiconductor layer there is provided a second conduction-type region extending to the light absorbing layer through the window layer. A part of the window layer around the second conduction region is selectively removed. Consequently even when light intended to enter a light detecting region is incident outside of the light detecting region, most of the carriers generated there are recombined at a surface level of the light absorbing layer before diffusing in a depletion layer. This light detecting device therefor does not substantially detect sensitivity to light incident outside the light detecting region.
