Abstract

We show that ghost waves—a special class of nonuniform waves in biaxial dielectric media—can lead to exact frequency degeneracies in guided modes. These degeneracies offer a new way of controlling mode interactions with a broad range of potential applications, from integrated waveguides to nonlinear optics and optical sensing.
