The device is a gas/vapor/aerosol/particulate sensor with a receiver/transmitter option. This optical MEMS device is designed to be a self-contained optical bench, integrating of an entire interferometer into a MOEMS‘optical bench’system-on-a-chip, and includes multiplexed optical path sensors. The sensing structures consist of laser sources, semiconductor photo detectors, refractive/reflective optical elements, and specialized optical transmission paths. Each individual laser source and photodiode is an optical path sensor with a particular‘functionalization.’These sensing arm functionalizations are sensitive to unique chemical signatures and as a result can recognize and report various chemical agents present in the ambient environment.
