• Gas Sensing Using Polymer-Functionalized Deformable Fabry–Perot Interferometers 

      St-Gelais, Raphael; Peter, Yves-Alain; Mackey, Gillian; Saunders, John; Zhou, Jingjing; Leblanc-Hotte, Antoine; Poulin, Alexandre; Barnes, Jack A.; Loock, Hans-Peter; Brown, R. Stephen (2016-03-03)
      We report a chemical vapor sensor in which polymer swelling, upon analyte absorption, is used to deform an on-chip silicon Fabry–Perot interferometer (FPI). The magnitude of the deformation, recorded through the resonance ...
    • Modeling of Fiber-Optic Fluorescence Probes for Strongly Absorbing Samples 

      Munzke, Dorit; Saunders, John; Omrani, Hengameh; Reich, Oliver; Loock, Hans-Peter (2016-03-08)
      The dynamic range of fiber-optic fluorescent probes such as single fibers and fiber bundles is calculated for strongly absorbing samples, such as process liquids, foodstuffs, and lubricants. The model assumes an excitation ...
    • Three-Wavelength Tm3+:ZBLAN Fiber Laser and its Applications in Water Detection 

      Jia, Chenglai; Ramaswamy, Kishor; Chen, Lawrence R.; MacLean, Amy G.; Andrews, Nicholas L. P.; Saunders, John; Barnes, Jack A.; Loock, Hans-Peter; Saad, Mohammed (2016-02-25)
      We demonstrate a three-wavelength Tm3+:ZBLAN fiber laser emitting simultaneously at 1460 nm, 1503 nm, and 1873 nm and its application in single-pass absorption measurements for detecting and quantifying water concentration ...
