It is based on using Brillouin optical time-domain analysis to probe the power distribution of the four-wave mixing generated by two continuous-wave lasers. The results obtained prove that this new method is capable of providing better performance than comparable techniques. Furthermore, sensing the variations of Brillouin gain maximum produces additional information about the fiber, such as presence of strain and concentration of GeO2. © 2003 Optical Society of America.Optical fibersFour wave mixingBrillouin scatteringRayleigh scatteringContinuous wave lasersGermanium compoundsNondestructive examinationTime domain analysistext::journal::journal article::research article
