ABSTRACT:
A single mode optical waveguide is fabricated in a manner such that the core thereof is subjected to a stress-induced birefringence. This characteristic is accomplished by introducing into the cladding region of the fiber on opposite sides of the core longitudinally extending regions of glass having a thermal coefficient of expansion different from that of the remainder of the cladding. A number of novel techniques are disclosed for forming such a fiber.
