摘要：A method for fabricating a transformer of linearly polarized light to ellipticallypolarized light is presented. The method involves twisting a birefringent fiber throughangles that depend on the polarization desired. This technique obviates the need tosplice fibers, as in common approaches. In the final step of the method, the polarization
can be fine tuned by heating the fiber to cause the core of the fiber to diffuse into thecladding. Using this transformer of polarized light, a current sensor is presented thatexploits the Faraday Effect in a Sagnac interferometer.
