Characterization of the Brillouin-loss spectrum of single-mode fibers by use of very short (<10-ns) pulses.

The characterization of the Brillouin-loss spectrum of single-mode fibers with very short (<10-ns) pulses has been studied. It was found that the Brillouin-loss signal intensity is linearly related to the duration of the pump pulse used to obtain the spectrum. In contrast with the uniform trend of the signal, three distinct behaviors were observed in the… CONTINUE READING
