    • Calibrating single-ended fiber-optic Raman spectra distributed temperature sensing data. 

      Hausner, Mark B; Suárez, Francisco; Glander, Kenneth E; van de Giesen, Nick; Selker, John S; Tyler, Scott W (Sensors (Basel), 2011)
      Hydrologic research is a very demanding application of fiber-optic distributed temperature sensing (DTS) in terms of precision, accuracy and calibration. The physics behind the most frequently used DTS instruments are considered ...
    • 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 ...
    • Instrument independent diffuse reflectance spectroscopy. 

      Yu, Bing; Fu, Henry L; Ramanujam, Nirmala (J Biomed Opt, 2011-01)
      Diffuse reflectance spectroscopy with a fiber optic probe is a powerful tool for quantitative tissue characterization and disease diagnosis. Significant systematic errors can arise in the measured reflectance spectra and ...
    • 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 ...
