摘要: Air-clad glass microring resonators vertically coupled to buried channel waveguides are experimentally investigated. Ring radii of 10 /spl mu/m, and drop bandwidths 5 nm reported. Vertical coupling eliminates the need for etching fine features, relaxes alignment resonator with respect input output bus waveguides.
