    • FSBS resonances observed in a standard highly nonlinear fiber. 

      Wang, Jing; Zhu, Yunhui; Zhang, Rui; Gauthier, Daniel J (Opt Express, 2011-03-14)
      Forward stimulated Brillouin scattering (FSBS) is observed in a standard 2-km-long highly nonlinear fiber. The frequency of FSBS arising from multiple radially guided acoustic resonances is observed up to gigahertz frequencies. ...
    • High-fidelity, broadband stimulated-Brillouin-scattering-based slow light using fast noise modulation. 

      Zhu, Yunhui; Lee, Myungjun; Neifeld, Mark A; Gauthier, Daniel J (Opt Express, 2011-01-17)
      We demonstrate a 5-GHz-broadband tunable slow-light device based on stimulated Brillouin scattering in a standard highly-nonlinear optical fiber pumped by a noise-current-modulated laser beam. The noisemodulation waveform ...
    • Information-theoretic analysis of a stimulated-Brillouin-scattering-based slow-light system. 

      Lee, Myungjun; Zhu, Yunhui; Gauthier, Daniel J; Gehm, Michael E; Neifeld, Mark A (Appl Opt, 2011-11-10)
      We use an information-theoretic method developed by Neifeld and Lee [J. Opt. Soc. Am. A 25, C31 (2008)] to analyze the performance of a slow-light system. Slow-light is realized in this system via stimulated Brillouin scattering ...
    • Slow light with a swept-frequency source. 

      Zhang, Rui; Zhu, Yunhui; Wang, Jing; Gauthier, Daniel J (Opt Express, 2010-12-20)
      ct: We introduce a new concept for stimulated-Brillouin-scattering-based slow light in optical fibers that is applicable for broadly-tunable frequency-swept sources. It allows slow light to be achieved, in principle, over ...
    • Theory and Application of SBS-based Group Velocity Manipulation in Optical Fibers 

      Zhu, Yunhui (2013)
      All-optical devices have attracted many research interests due to their ultimately low heat dissipation compared to conventional devices based on electric-optical conversion. With recent advances in nonlinear optics, it ...
