An exciting new area of research that we are focusing concentrates around the realization of nano-structured metamaterials and related optical components for applications such as super-resolving microscopes, nanoscale sensors, the enhancement of the resolution of optical lithography and the implementation of dense optoelectronic circuits for telecommunication applications. In this effort we are seeking new avenues and techniques for translating some of the microwave metamaterial concepts, components and structures that we have developed in the past to the optical domain. A related research activity is the creation of unique nano-antennas for imaging and sensing applications and for harnessing light.
