    • Terahertz waveguiding in glass+clad silicon wafers 

      Sørgård, Trygve; Mølster, Kjell Martin; Laurell, Fredrik; Pasiskevicius, Valdas; Gibson, Ursula; Österberg, Ulf Lennart (Journal article; Peer reviewed, 2020)
      The waveguiding properties of high-resistivity float zone silicon slab waveguides are characterized over the spectral range from 0.5 to 7.5 THz. Waveguide modes and dispersion are observed for lengths of 1.2 cm and silicon ...

    • Time-domain spectroscopy of KTiOPO4 in the frequency range 0.6 - 7.0 THz 

      Mølster, Kjell Martin; Sørgård, Trygve; Laurell, Hugo; Canalias, Carlota; Pasiskevicius, Valdas; Laurell, Fredrik; Österberg, Ulf Lennart (Journal article; Peer reviewed, 2019)
      We report on THz time-domain spectroscopy measurements of flux grownKTiOPO4in the frequency range 0.6–7.0 THz (20 to 240 cm−1). Our results compare well with earlierRaman and far-infrared measurements. We theorize that the ...
