    • All-optical high-speed modulation of THz transmission through silicon core optical fibers 

      Sørgård, Trygve Reinertsen; Hawkins, Thomas; Ballato, John; Österberg, Ulf Lennart; Gibson, Ursula (Journal article; Peer reviewed, 2021)
      High speed optical modulation of THz radiation is of interest for information processing and communications applications. In this paper infrared femtosecond pulses are used to generate free carriers that reduce the THz ...

    • Continuous-wave Raman amplification in silicon core fibers pumped in the telecom band 

      Huang, Meng; Sun, Shiyu; Wu, Dong; Ren, Haonan; Shen, Li; Hawkins, Thomas; Ballato, John; Gibson, Ursula; Peacock, Anna C. (Peer reviewed; Journal article, 2021)
      Stimulated Raman amplification is observed for the first time in the silicon core fiber (SCF) platform. The SCFs were tapered to obtain sub-micrometer core dimensions and low optical transmission losses, facilitating ...

    • Net optical parametric gain in a submicron silicon core fiber pumped in the telecom band 

      Wu, Dong; Shen, Li; Ren, Haonan; Campling, Joseph; Hawkins, Thomas; Ballato, John; Gibson, Ursula; Peacock, Anna (Peer reviewed; Journal article, 2019)
      A silicon core fiber (SCF) has been designed and fabricated with a dispersion engineered profile to support broadband optical parametric amplification across the telecom window. The combination of low optical transmission ...
