Abstract

A fiber to planar waveguide coupling structure incorporating a thin metal layer is described. The resonant wavelengths for the TM polarization were found to be highly sensitive to the refractive index of the superstrate material while those for the TE polarization were unaffected. A theoretical model for the multilayer structure was developed on the basis of a matrix method approach and a preliminary analysis of the resonance shift phenomena for the TM mode shows good agreement with experiment.<>
