Abstract
In the present invention, a multilayer stack of alternating layers of a metal and a dielectric is deposited directly onto the surface of an optical fiber that has been processed to remove the cladding from one side of the fiber. The multilayer metal-dielectric structure is constructed to give high birefringence and large differential attenuation for two orthogonal polarizations.
