  • Abstract
    Triethyl phosphate (TEP), a chemical warfare simulant, has absorption peaks in the mid-infrared. Using a single mode slot wave guide we were able to detect TEP, with a detection limit down to 75 ppm. This provides enhanced sensitivity while simultaneously achieving device miniaturization.
