Abstract
A single mode optical waveguide is constructed in a manner such that the core thereof is subjected to a stress-induced birefringence. The fiber comprises an oblong core surrounded by an oblong inner cladding layer. An outer layer of stress cladding glass, which has a circular outer surface, surrounds the inner cladding layer. The TCE of the stress cladding glass is different from that of the inner cladding glass.
