Abstract

We report measurements of the guided-wave reflectivity of a periodic, surface-corrugation, waveguide grating as a function of incidence angle and polarization. We show that the measured response is more accurately described by a coupled-mode theory based on the local-normal-mode expansion of the fields than by that based on the ideal-mode expansion.
