On-chip Nanophotonic Transducers for Ultra-sensitive, Ultra-fast and Low-cost Chemical Treat Sensing
Abstract
Future military sensing of chemical threat materials requires fine resolution, multiple modalities, and highly dynamic operation in order to fulfill a broad range of warfighter needs such as protection and security, persistent surveillance, target recognition and tracking, and early warning of threats. Compared with chemical sensing techniques such as gas chromatograph-mass spectroscopy, electrochemical sensing and patch chemical reaction sensing, photonic sensing based on spectroscopic techniques represents a very promising approach for low-power, lowconsumable chemical detection. In this project, we will design and fabricate miniaturized photonic transducers by integrating on-chip light sources and detectors, in order to significantly reduce the response time and cost of current photonic sensing devices. Specifically, by taking advantage of infrared molecular fingerprints of chemical analytes, we will not only expand the sensing selectivity to the broad infrared range but also develop ultra-sensitive chemical detection for high-fidelity molecular identification.
