Abstract

We discuss the propagation characteristics of the electromagnetic field in the symmetric metal-clad planar uniaxial crystal waveguide. For the special waveguide structure that the optical axis of the crystal is on the x-z plane, where x is the normal direction of the waveguide plane and z is the propagation direction, we obtain the analytic accurate solution of the modal fields. It is shown that:(1) there are TE mode and TM mode in this special waveguide structure; 2) The direction of the wave vector and the Poynting vector of TM mode are not collinear; (3) The principal mode of the waveguide is the principal mode of TE mode for the negative uniaxial crystal, but the one of TM mode for the positive uniaxial crystal.
