Ring or disc optical resonators are provided with random or coherent corrugation on a top surface to cause optical power to be radiated in a desired direction by light scattering. The resonators may be positioned proximate a waveguide, either in-plane or inter-plane with the waveguide. The resonators...http://www.google.es/patents/US20040240782?utm_source=gb-gplus-sharePatente US20040240782 - Light scattering optical resonator
