  • Abstract
    The role of a dielectric buffer in the polarisation selectivity of a PbSe (cladding)/BaF2/CaF2 waveguide having transmission passband in the infrared wavelength of 3.4 μm is investigated. Results indicate that the presence of a buffer layer can greatly enhance the polarisation extinction ratio in such semiconductor-clad waveguides, enabling their use as a polarisation selector
