Abstract
A cpylindrical nematic liquid-crystal waveguide with an infinite homogeneous isotropic cladding is considered. The dielectric tensor of the liquid-crystal core that governs wave propagation is determined by the configuration of the nematic director. Propagating optical fields can alter the director configuration and thus change the dielectric tensor. We use an iterative numerical scheme to determine the propagation constant as a function of optical power.
