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