Abstract
A correlation spectrometer can include a sample cell, a plasmonic array, a light source that can be used to illuminate both the plasmonic array and the sample cell, and an infrared (IR) detector that is connected to the plasmonic array, and that is configured to receive and detect surface plasmons. The plasmonic array is modulated to transmit a surface plasmon at a predetermined resonance peaks that correspond to resonant peaks for a compound of interest (COI). If the COI is present in the sample cell, a surface plasmon having resonant peaks corresponding to the COI resonant peaks is generated in the plasmonic array and detected by the IR detector. The plasmonic can be formed with a plurality of nanoholes with different periodicities and fill factors, in order to detect multiple COI.
