ABSTRACT:
A photodetector module including a support substrate having a main surface, an optical waveguide mounted on the support substrate and having an end face for emerging a light beam along a first optical path, and a photodetector mounted on the support substrate so that the light beam emerged from the end face of the optical waveguide is incident on the photodetector, the photodetector having a photodetecting portion responding to the light beam incident on the photodetector. The photodetector module further includes a first inclined surface formed on a substrate of the photodetector for refracting the light beam along the first optical path to a second optical path, and a second inclined surface for totally reflecting the light beam along the second optical path to a third optical path substantially perpendicular to the photodetecting portion.
