ABSTRACT:
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 are used in a polymeric photonic display. Light at each fundamental color is generated by light emitting diodes, such as organic light emitting diodes (OLEDs). The light is coupled into waveguides that cross an array of diffractive elements, such as the resonators, each combined with an optical modulator, such as a polymer electro-optic (EO) modulator. The modulator allows light from the waveguides to reach the diffractive elements. Control lines run across the waveguides, and provide control signals to the modulators, allowing one row of diffractive elements at a time to receive light from the waveguides. The rows are scanned and synchronized with light generated by the OLEDs.
