Distributed sensing of temperature using Stimulated Brillouin scattering

We review the basic concepts of Brillouin Scattering in an optical fiber, and its application in distributed sensing of temperature and strain. We show the simulation results which will provide a basic understanding of Stimulated Brillouin scattering and stimulated Brillouin amplification in an optical fiber. We further review the different configurations in which Brillouin scattering could be used for physical parameter sensing. We simulate the characteristics of Brillouin amplification process in a standard single mode fiber in the continuous and pulsed mode. These results would help in further developing a foolproof method for the measurement of temperature/strain.
