Power Distribution in a Chirofiber Filled with Distinct Core and Cladding Chiralities

Abstract

In this paper a theoretical study of the power distribution in the core and the cladding of a chirofiber in which these regions are filled with homogeneous chiral materials of distinct chiralities for two lowest azimuthal modal indices is made. The general expressions for the power in the core and the cladding are derived after solving the wave equations and determining the field components. The effect of chirality on the power distribution is studied for two special cases: when (i) chirality is present only in the cladding and (ii) chirality is present only in the core. Numerical computations are made in each case and some interesting results showing the possibility of application in devices in integrated optics are obtained. It is found that the presence of chirality in the cladding confines the total power to the core region for the higher order modes but for the lowest order mode some power gets into the cladding. Another interesting feature emerges in the result that the power distribution shows a fluctuating variation with the core chirality. © 1995 Academic Press, Inc.
