Patent ID: 8378289

Claim:
An optical receiver module for receiving light which is entered through an optical fiber connected thereto, comprising: a light-receiving element; and a support member for supporting the light-receiving element, wherein: the light-receiving element is arranged at a position shifted from a position on an optical axis of the optical fiber; and the light-receiving element is arranged such that: a shift perpendicular plane, which is a plane including an intersecting point between the optical axis of the optical fiber and a surface of the support member on a side facing the light-receiving element, is perpendicular to said surface, the shift perpendicular plane is perpendicular to a line intersecting with the optical axis of the optical fiber, said line being from a light-beam intersecting point, which is an intersecting point between the entered light and a light-receiving surface of the light-receiving element, and the shift perpendicular plane is not parallel to a direction of a nearest edge of the light-receiving element, the nearest edge being contained in the surface of the support member on the side facing the light-receiving-element and being nearest, among all edges of the light-receiving element, to the intersecting point between the optical axis of the optical fiber and the surface of the support member on the side facing the light-receiving element.
