Abstract

Electromagnetic wave propagation through an achiral-chiral interface is analyzed via Maxwell's equations using the appropriate boundary conditions. Experimental data for reflected power from achiral-chiral interface was found to be in qualitative agreement with the analytical results. In addition, coupled mode equations for chiral cladding waveguides were derived and solved for weak coupling. The experimental results of chiral cladding waveguides show that an average of about 0.2° per cm in polarization rotation occurred. These waveguides were fabricated by using spin-coating deposition. The sense of the rotation was found to be independent of the handness of the cladding chirality, which was predicted analytically.
