Numerical analysis of temporal stimulated Brillouin scattering in optical fiber

Using numerical calculation the distribution of pump wave, Stokes wave and sound wave in optical fiber during the whole SBS process can be achieved, which is useful to analyze the transient SBS processing and the influence of SBS reflectivity and threshold from the fiber length, pump pulse width. Hereby a new type of fiber phase conjugator with adjust able core radius is shown in this paper.
