Paper Abstract

An optical resonance phenomena, based on an interference effect that occurs when a plane wave is incident on a dielectric grating/waveguide structure, is presented. The incident wave excites a guided mode in the waveguide which in turn is partially diffracted by the grating in the direction of the transmitted zero order beam, interfering destructively. As a result most of the light energy is contained in the reflected zero order beam. This resonance phenomena is explained with a ray picture of the multiple interference and analyzed by solving Maxwell's equations for the exact eigenfunctions in a grating/waveguide structure. Some basic structures have been fabricated and experimentally tested. The results reveal that the resonance beamwidth and bandwidth depend strongly on the parameters of the grating/waveguide structure. Measurements indicate that the bandwidth of the resonances can be as narrow as 1 nm, with a corresponding angular beamwidth on the order of minutes of arc.
