ABSTRACT:
A single-mode optical waveguide is constructed in a manner such that the core thereof is subjected to a stress-induced birefringence. A single-mode optical fiber preform is formed by a CVD process. A pair of longitudinally extending holes is formed on opposite sides of the core, spaced slighty therefrom. A stress rod having a TCE different from that of the cladding portion of the preform is inserted into each hole. The space between the holes and the rods is evacuated. The resultant composite structure is drawn into an optical fiber. A similar method is used to form a fiber having multiple light conducting cores, this method differing in that the rods which are inserted into the holes are formed of a glass having a refractive index greater than that of the cladding portion of the preform.
