    • 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, ...

    • Towards Mid-IR Waveguide Lasers: Transition Metal Doped ZnS Thin Films 

      Karhu, Eric Andrew; Tolstik, Nikolai; Sorokin, Evgeni; Polyakov, Stanislav; Zamiri, Reza; Furtula, Vedran; Østerberg, Ulf Lennart; Sorokina, Irina T; Gibson, Ursula (Chapter; Peer reviewed, 2016)
      Thin films of Cr and Fe-doped ZnS suitable for waveguide mid-IR applications, with well-isolated TM2+ peaks, and Cr2+ absorption and fluorescence comparable to bulk crystals were investigated. Raman data indicate that the ...
