Stimulated Brillouin scattering for generating an acoustic wave in optical fibers

We present our first basic concept of the simulation of stimulated Brillouin scattering (SBS) in this paper. We summarize basic theories of SBS in standard communication optical fibers. We are using the simulation to recognize effects of using SBS to generate acoustic waves in fibers. The acoustic waves in the optical fibers can be used to create long period fiber grating. We present our application of this effect in our concept of fiber spectrometer and optical filters. Basic principle of these applications is in the interaction of acoustic waves with measured laser beam in the optical fiber. The interaction of acoustic waves and the measured laser beam in the optical fiber is demonstrated.
