    • Extraordinary evanescent field confinement waveguide sensor for mid-infrared trace gas spectroscopy 

      Vlk, Marek; Datta, Anurup; Alberti, Sebastian; Yallew, Henock Demessie; Mittal, Vinita; Murugan, Ganapathy Senthil; Jágerská, Jana (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-01-29)
      Nanophotonic waveguides are at the core of a great variety of optical sensors. These structures confine light along defined paths on photonic chips and provide light–matter interaction via an evanescent field. However, waveguides still lag behind free-space optics for sensitivity-critical applications such as trace gas detection. Short optical pathlengths, low interaction strengths, and spurious ...

    • Integrated nanophotonic waveguide-based devices for IR and Raman gas spectroscopy 

      Alberti, Sebastian; Datta, Anurup; Jágerská, Jana (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-10-30)
      On-chip devices for absorption spectroscopy and Raman spectroscopy have been developing rapidly in the last few years, triggered by the growing availability of compact and affordable tunable lasers, detectors, and on-chip spectrometers. Material processing that is compatible with mass production has been proven to be capable of long low-loss waveguides of sophisticated designs, which are indispensable ...
