Abstract :
A novel means of implementing periodicity into a glass fiber, which allows for polarization as well as wavelength selectivity is investigated. Three types of polarization sensitive chiral fiber gratings are studied: (1) chiral long-period gratings (CLPGs) which resonantly couple core modes to copropagating cladding optical modes, (2) nonresonant chiral intermediate-period gratings (CIPGs) which scatter light out of the core, and (3) resonant chiral short-period gratings (CSPGs) which reflect light within the fiber core. Each of these gratings interacts only with circularly polarized light with the same handedness as the grating and freely transmits light of the orthogonal polarization.
