1. A polarizing fiber optic waveguide, comprising:

  • a core formed of a plurality of alternating dielectric layers, each layer having a characteristic refractive index, said core being formed such that the dielectric layers provide a first core refractive index for light of a first polarization and a second core refractive index for light of a second polarization; and

    a cladding surrounding said core, said cladding being formed of a dielectric material having a refractive index at least as large as said first core refractive index and less than said second core refractive index such that said core guides only light of said second polarization and light of all other polarizations propagate from said core into said cladding.
