Patent ID: 8118498

Claim:
An optical receptacle which is configured to abut an optical package which comprises a disk-shaped stem, a lens support which is formed on an inner surface of the stem, a lens which is supported by the lens support, and a light-receiving element which is contained in the lens support, comprising: a main body having a recess for receiving the lens and the lens support, and a through hole penetrating from a bottom of the recess toward an exterior and configured for an optical fiber to be inserted therethrough from the exterior, the recess and the through hole being in direct communication with each other, wherein the through hole is configured so that an optical axis of the inserted optical fiber and a center axis of the through hole are substantially collinear, the recess is formed so that the inserted lens is disposed on the center axis of the recess, one end of the through hole of the main body opens at a position deviated from the center of the bottom surface of the recess so that light output from a tip of the inserted optical fiber and passing the lens is collected to the light receiving element when the optical receptacle is abutted by the optical package, a substantially uniform gap is formed between an inner peripheral surface of the recess and an outer peripheral surface of the lens support when the optical receptacle is abutted by the optical package, and an opening end surface of the recess formed in the main body is configured to be in abutment with the inner surface of the stem.
