Investigation of stimulated Brillouin scattering spectra of an optical fiber with use of a frequency modulated laser
We demonstrate a method to characterize the gain spectrum of Stimulated Brillouin scattering in an optical fiber by using two tunable laser sources in CW. Brillouin amplifier configuration is used, in which one laser is used to create SBS in the fiber. Light from the other laser is frequency modulated and counter-propagated in the fiber in order to extract the SBS gain spectrum. Experimental results are presented to demonstrate the gain bandwidth and the Brillouin frequency shift. This method does not need high-speed modulator or detectors, and does not use heterodyne measurements.
