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.
