Nanostructuring for interaction with light

This activity focuses on the development of low-cost, reliable infra-red gas sensors based on silicon microsystems technology. This includes realization of key components such as IR sources, tunable filters and silicon based IR detectors. Other research has focused on the design, fabrication and characterization of a novel piston-type micromirror with a stroke of up to 20 µm at 20 V formed out of a silicon-on-insulator wafer with integrated piezoelectric actuators. Another area of effort involves a novel design for an optical biological sensor, which uses readout techniques exploiting 2D photonic crystals to improve its sensitivity. The goal is single-molecule sensitivity, which can be employed in antibody-antigen reactions, DNA hybridization, and protein-protein interactions.
