Abstract
A polarizing optical waveguide comprising a birefringent core surrounded by an isotropic medium wherein the dielectric constant of the birefrigent medium is .epsilon..sub.TE for the plane of polarization parallel to the surface of the medium and .epsilon..sub.TM for the plane of polarization perpendiuclar to this surface and the dielectric constant of the isotropic medium is .epsilon..sub.i. In order to selectively confine the TE mode, the relationship between the dielectric constants is .epsilon..sub.TM <.epsilon..sub.i <.epsilon..sub.TE.
