• Free-standing tantalum pentoxide waveguides for gas sensing in the mid-infrared 

      Vlk, Marek; Datta, Anurup; Alberti, Sebastian; Murugan, Ganapathy Senthil; Aksnes, Astrid; Jagerska, Jana (Peer reviewed; Journal article, 2021)
      Typical applications of integrated photonics in the mid-infrared (MIR) are different from near-infrared (telecom) range and, in many instances, they involve chemical sensing through MIR spectroscopy. Such applications ...
    • Nonlinear optical response and structural properties of MBE-grown Fe:ZnS films 

      Polyakov, Stanislav; Karhu, Eric Andrew; Zamiri, Reza; Moisset, Charles; Iliopoulos, Konstantinos; Vullum, Per Erik; Österberg, Ulf; Gibson, Ursula (Journal article; Peer reviewed, 2018)
      Fe-doped ZnS films of high optical quality were fabricated using vacuum vapor deposition. Preferential crystalline orientation and phase purity of the host ZnS films were increased by the addition of small amounts of Fe, ...
