title: Polarization properties of evanescent couplers.
abstract: While there have been several attempts recently to extend the accuracy of vector coupled-mode theory beyond the usual first-order expression for evanescent couplers, as yet no analytical method is available for describing the polarization properties of couplers with a large core-cladding index jump. Here we present a quasi-static approximation for couplers of low V value, where V is the usual waveguide parameter.
