7 March 2014 Experimental study of SBS suppression via white noise phase modulation
Author Affiliations +
White noise phase modulation is an effective technique capable of increasing the SBS threshold in high power fiber amplifiers. Theoretical models predict the enhancement factor as a function of linewidth and fiber length, but have yet to be experimentally verified over wide ranges of these variables. We present results on a cut-back experiment performed on a passive fiber with a white-noise broadened laser, measuring the SBS enhancement factor as a function of fiber length and bandwidth. In addition, the experimental results will be compared to phase modulation models of the SBS process in optical fibers.
