OPTICAL WAVEGUIDE WITH RADIATION-TUNED BIREFRINGENCE

摘要

A radiation tuned optical fiber comprises an optical fiber that includes a substantially circular core and a cladding containing an asymmetric stress zone. The substantially circular core has an initial birefringence. A length of the optical fiber has at least one radiation-tuned portion wherein the substantially circular core has a tuned birefringence to provide the radiation tuned optical fiber in which the tuned birefringence differs from the initial birefringence.
