Abstract
Radiation of leaky modes existing in anisotropic waveguides can be cancelled by destructive
interference at special propagation directions relative to the optical axis orientation, resulting in
fully bound states surrounded by radiative modes. Here we study the variation of the loci of such
special directions in terms of the waveguide constitutive parameters. We show that the angular
loci of the bound states is sensitive to several design parameters, allowing bound states to exist for
a broad range of angular directions and wavelengths and suggesting applications in filtering and
sensing.
