Abstract

We show that a chiral film that is not matched to the refractive indices of the surrounding media behaves as a Bragg resonator for elliptically polarized light with a given handedness, ellipticity, and axial alignment. Equations are derived for the polarization parameters, auxiliary angle (chi) and azimuthal angle (alpha), of the polarization ellipse. Thickness modulated chiral films and chiral-birefringent composite media are considered as elliptical Bragg mediums. Experimental results are presented for coatings fabricated with titanium oxide.
