Optical receiver module

摘要

An optical receiver module capable of increasing the range in which the error in distance between a collecting lens and a light receiving section is allowed is provided. In the optical receiver module according to the invention, the optical receiver includes a semiconductor substrate to which the light from the collecting lens is input, and through which the light passes, and a light receiving section disposed on a side (a reverse side) of the semiconductor substrate, the side being further from the collecting lens, and adapted to receive the light transmitted through the semiconductor substrate, and then convert the light into an electrical signal. On a side (an obverse side) of the semiconductor substrate, the side being nearer to the collecting lens, there is formed a lens surface adapted to converge light from the collecting lens toward the light receiving section.

1. An optical receiver module comprising:
a collecting lens; and an optical receiver adapted to receive light from the collecting lens, wherein the optical receiver includes a semiconductor substrate to which the light from the collecting lens is input, and through which the light passes, and a light receiving section, which is disposed on a further side of the semiconductor substrate from the collecting lens, adapted to receive the light having passed through the semiconductor substrate, and then converts the light into an electrical signal, and a lens surface adapted to converge the light from the collecting lens toward the light receiving section is formed on a nearer side of the semiconductor substrate from the collecting lens, wherein a focal point, of the light output from the collecting lens and reaching the light receiving section via the semiconductor substrate, is located inside the semiconductor substrate and between the lens surface and the light receiving section.
