Abstract
The present invention provides an optical receptacle capable of reducing the optical coupling loss with the connector plug to be mated with the receptacle, and an optical module installing the receptacle. The receptacle of the invention includes an optical waveguide, a stub, and a body. The stub includes a first bore, into which the waveguide is disposed, and a second bore. The waveguide may be made of same material as that constituting the core of the optical fiber, and may have a substantially same diameter as that of the cladding. Thus, the aperture for coupling the optical fiber may be expanded.
