Anomalous phase in one-dimensional multilayer periodical 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 polarizatin component of the transmitted field increases with wavelength, giving rise to unusual polarization dependent dispersive effects of the input beam. We have analysed the delay obtained with birefringent one-dimensional multilayer structures and the effect of the dispersion in the materials to generate anomalous phase in the spectrum.
