Simultaneous mid-infrared gas sensing and upconversion based on third harmonic generation in cascaded waveguides

The performance of conventional gas sensors based on light absorption in the mid-infrared are limited by the high-cost and low efficiency of photon detection at these wavelengths. In this paper, cascaded suspended waveguides are proposed and analyzed for mid-infrared gas sensing with enhanced detect...
