Abstract
This invention relates to fiber optic apparatus and methods for polarizing light for use in fiber optic devices, such as rotation sensors. A phase grating (52) formed of alternating layers of dielectrics (54,56) having different indices of refraction is placed adjacent a half coupler (12) that includes a fiber (20,22) having a cladding thickness which forms an interaction region. The evanescent field of light of a selected polarization interacts with the phase grating (52) to couple out of the fiber (20,22) while light of a second selected polarization remains in the fiber (20,22).
