Abstract

Forward stimulated Brillouin scattering (FSBS) between two co-propagating optical waves is observed in 220 meterslong sections of standard single-mode fibers. The interaction is mediated by high-order, radial acoustic modes that are supported by the fiber. The acoustic resonance frequency and the gain spectrum of an individual mode are characterized using a single-frequency stimulation procedure, with no need for frequency scanning. The measurement protocol is employed in the characterization of the temperature dependence of the resonance frequency. Good agreement with previous literature is achieved. The temperature sensitivity of the measurements is ±0.65 °C.
