Abstract

During the stimulated Brillouin scattering in multimode fiber, the Brillouin gain of different mode of the signal beam is affected by the property of both the light modes and acoustic modes in waveguides. In our study, the stimulated Brillouin scattering process in two-mode fiber is investigated, both experimentally and numerically, based on the mode characteristics of light field and acoustics field. The results indicate that the Brillouin gain of corresponding combination of signal-pump modes is determined by the overlapping area of optics-acoustic mode fields.
