Abstract: Devices and methods for non-dispersive infrared (NDIR) sensing are disclosed. In one aspect, a non-dispersive infrared sensor is disclosed which, in one embodiment includes a nanophotonic infrared emitting metamaterial (NIREM) emitter configured to selectively emit radiation corresponding to a respective vibrational resonance frequency for each of a plurality of different analytes of interest. The broadband detector can be configured to detect photons associated with vibrational resonance of each of the plurality of analytes of interest in response to the emitted radiation from the NIREM emitter, in order to determine properties of one or more of the analytes of interest.

Abstract: A device includes a substrate having a pattern of surface features on a surface thereof, and a layer including a material having an Epsilon-Near-Zero (ENZ) condition for a wavelength range. The layer extends on the surface of the substrate and along the pattern of surface features. Related devices and fabrication methods are also discussed.
