Optical subassembly and related methods for aligning an optical fiber with a light emitting device

摘要

An optical subassembly for aligning an optical fiber with a light emitting device includes a fiber optic stub mounted in a ferrule and a v-groove device coupled to the ferule with a loose end of the fiber optic stub lying in the v-groove device. The other end of the fiber optic stub is polished. According to methods contemplated by the invention, the ferrule is mounted in a ring which is welded to a light emitting subassembly. The unpolished loose end of the fiber optic stub self-aligns with a mating fiber in the v-groove device. According to the presently preferred embodiment, the v-groove device is provided with s-bends which aid in self-alignment between the loose fibers.
