Abstract

See full text

An optical receptacle and an optical module that implements the optical receptacle are disclosed. The optical receptacle provides a stub holding a coupling fiber in a center thereof, a bush press-fitting the stub therein, a sleeve, and a metal cover that is to be welded to an external metallic member. The coupling fiber has a type of polarization maintaining fiber. The bush is inserted into the cover as leaving a gap between the cover and the bush. The gap between the cover and the bush effectively relaxes or absorbs stresses induced during the welding caused in the coupling fiber.
