ABSTRACT:
A polarized optical fiber, having inherent birefringence provided by electrically induced orientation of its microcrystalline structure provides fixed polarization. In the method, an optical fiber having inherent birefringent characteristics is formed by heating a glass optical fiber preform to its drawing temperature, drawing the preform to reduce its diameter and cooling the resulting fiber in the presence of an applied electric field to fixedly orient the microcrystalline structure of the fiber to provide birefringent light transmitting characteristics.
