Patent ID: 7387450

Claim:
An optical receptacle for receiving an optical connector plug that secures an optical fiber with a core and a cladding surrounding the core, and for connecting the optical fiber with an optical device including a light emitting device, said optical receptacle comprising: an optical waveguide made of material having a homogeneous refractive index; a cylindrical stub with a uniform outer diameter, said stub including a first bore and a second bore continuous with said first bore, said first bore securing said optical waveguide therein at a location upstream of the optical fiber of an optical connector plug received by said optical receptacle, said second bore being at a location upstream of said first bore and downstream of the light emitting device of an optical device connected to an optical connector plug by said optical receptacle; and a sleeve having a first portion and a second portion along an optical axis of said sleeve, said first portion of said sleeve receiving a portion of said stub and said second portion of said sleeve receiving an optical connector plug, wherein said second bore of said stub has a diameter greater than a diameter of said first bore, and wherein a length of said second bore along an optical axis of said stub is longer than a length of said first bore along said optical axis.
