Abstract
The ends of a pair of polarization-maintaining optical fibers that each have an elliptical stress member in the cladding to produce stress induced birefringence are placed end-to-end with a predetermined gap between the ends of the fibers. The ends of the fibers are examined with an optical imaging apparatus whose focus is adjusted to locate an alignment band in each fiber. The position of one of the polarization-maintaining optical fibers is then adjusted until the two alignment bands are in longitudinal alignment. The fiber ends are pre annealed and then fused together by application of energy from an electric arc.
