Abstract

The cladding mode resonances of a tilted fiber Bragg grating show very strong polarization splitting for modes near cutoff, as determined by the surrounding refractive index. Rotating the linear polarization of the core guided light results in amplitude changes that can exceed 10 dB, but only for a few modes. The wavelengths of these highly sensitive modes can then be used to determine the surrounding refractive index.
