• Chemical Sensing Using Fiber Cavity Ring-Down Spectroscopy 

      Waechter, Helen; Litman, Jessica; Cheung, Adrienne H.; Barnes, Jack A.; Loock, Hans-Peter (2016-03-18)
      Waveguide-based cavity ring-down spectroscopy (CRD) can be used for quantitative measurements of chemical concentrations in small amounts of liquid, in gases or in films. The change in ring-down time can be correlated to ...
    • Near Infrared Absorption Detection in Picolitre Liquid Volumes Using Fiber Loop Ring-Down Detection 

      Andrews, Nicholas L. P.; Litman, Jessica; Stroh, Daniel; Barnes, Jack A.; Loock, Hans-Peter (2016-03-07)
      Cavity ring-down spectroscopy is performed using a single-mode fibre loop as an optical cavity. The loop contains absorption cells for either liquids or gases, as well as an erbium-doped fibre amplifier. The fibre amplifier ...
