The geometric mismatch between semiconductor lasers and single-mode optical fibers or diffused waveguides causes serious light loss. Transition fibers with cores that change shape from rectangular to circular can be used to reduce these losses. Techniques for fabrication of transition fibers with losses of 1 dB are discussed.
