Paper Abstract

Optical component coupling using self-written waveguides is one of the promising methods to improve the existing alignment control difficulties in optical component coupling. Using conventional UV curable resin as a waveguide material, waveguide spontaneously forms by UV light exposure from an edge of an optical fiber. When UV light is exposed from two faced optical fiber edges, self-written waveguide forms between them and connect the two optical fibers with decreasing its coupling loss between them. The effectiveness of this unique method is systematically studied on multi-mode fiber coupling; single mode fiber coupling can also be attained. The observed coupling loss after waveguide formation is significantly lower than that before the waveguide formation. Coupling of multi-mode fibers with not only gap but also some offset was also studied; the input light is actually bending and guiding along the formed self-written waveguide between two multi-mode fibers. Using this easy, quick and convenient coupling method, severe alignment control would not be required in a optical component coupling procedure and significant cost reduction could be expected.
