Organic Microring Resonators

Aim: Development of electro-optically active organic microring resonators for telecommunication applications. Approach: Design, high-resolution patterning and electro-optic characterization of microresonators in poled polymers and organic single crystals. Impact: High-speed VLSI photonics elements for switching, filtering and modulation.

Integrated Microring Resonators
a) A simplified scheme of a so-called Charon coupler, which was designed to achieve smaller polymer-device dimensions (<50 μm ring radius), enhancement of the coupling acceptance, and increased modulation bandwidth maintaining the large electro-optic sensitivity typical of high-Q resonators. Examples of (b) laterally and (c) vertically coupled 50 μm-radius electro-optic Charon microresonators produced by micro-embossing technique. The measured transmitted intensity shows strongly asymmetric Fano resonances with approximately linear steepest resonance edge.
