Semiconductor light-receiving device |
摘要 |
A semiconductor light-receiving device includes: a substrate; a p-type conductive layer, a light absorption layer having a smaller bandgap than that of incident light, a multiplication layer producing avalanche multiplication, and an n-type window layer laminated in that order on the substrate; an n-type conductive layer in a region of part of the n-type window layer; and a first p-type conductive region in a region of the n-type window layer that is not in contact with the n-type conductive layer, wherein the first p-type conductive region does not reach the multiplication layer and is not in contact with any electrode to which power is supplied from outside. |
