Anomalous phase in one-dimensional, multilayer, periodic structures with birefringent materials

Abstract

We have studied biaxial, birefringent, one-dimensional, multilayer structures and found a wavelength region where the phase of one specific polarization component of the transmitted field increases with wavelength, giving rise to unusual polarization dependent dispersive effects of the input beam. We discuss the conditions that lead to these effects, and examine possible ways to enhance them.
