Abstract:
An integrated fiber-ferrule useable as an optical coupling element includes a core directly contacting a cladding layer that has a lower index of refraction than that of the core, without an intervening adhesive. The cladding layer outer diameter is at least 100 times greater than that of the core, and matches an outer diameter of a standard ferrule. The integrated fiber-ferrule may be produced by drawing a glass preform into a cane, cutting the cane into sections, and shaping end faces of the cut sections (e.g., using a laser). To form a fiber optic assembly, a front end of an optical fiber core may be fusion spliced to a rear end of the core of the integrated fiber-ferrule. Use of an integrated fiber-ferrule permits reduction of core to fiber eccentricity, and reduction of connector insertion losses.

Claim (Index 15):
An optical coupling element configured as an integrated fiber-ferrule, the optical coupling element comprising:\n a core having a first index of refraction; and a cladding layer peripherally surrounding the core, wherein the cladding layer has a lower index of refraction than the core, and wherein the core is arranged in direct contact with the cladding layer without an adhesive arranged therebetween; wherein an outer diameter of the cladding layer is equal to or greater than 1 mm and is at least 20 times greater than an outer diameter of the core.
