Abstract
An integrated approach to optical sensing (˜cm3 excluding electronics) at concentrations of parts-per-million or less (ppm). The invention enables the trace detection of chemicals in fluids (gas or liquid) in a highly integrated package. The simultaneous detection of any number of Raman active molecular species (including isotopes) may be achieved in a scalable, low-cost manner.
