| Abstract(in English) | We propose a novel principle for generating the cascaded forward Brillouin scattering (CFBS) using a counter-propagating pump-probe technique. The basic concept of this principle is the use of backward stimulated Brillouin scattering as the seed of CFBS. The CFBS induced by FSBS is generated via the energy transfer from the probe light to other acoustic resonance frequencies. Subsequently, we experimentally observe the CFBS in a 390-m-long highly nonlinear fiber exploiting this principle. The measured CFBS has a high signal-to-noise ratio (SNR) and the center frequencies of its acoustic resonance peaks agree with theoretical values. Finally, we clarify the sensing properties of the generated CFBS, such as the SNR dependence on pump and probe powers and the CFBS frequency shift dependence on temperature. |
