Abstract
According to one embodiment, a semiconductor light-receiving element, includes a light-receiving part provided on a substrate and having a semiconductor multilayer structure of a circular outer shape, a optical input part formed of a peripheral portion of the semiconductor multilayer structure, and having a tapered front end, and a silicon-thin-line waveguide configured to couple light with the optical input part. The waveguide includes a linear part extending through the optical input part to an at least one area of an upper-side area and a lower-side area of the light-receiving part, and a spiral part connected to the linear part and formed in the at least one area.
