Paper Abstract

The refractive index changes induced by stimulated Brillouin scattering in an optical fiber are measured experimentally by polarization-decoupled four-wave mixing. Under undepleted pump approximation, net phase-matching condition depends on pump power and frequency detuning from Brillouin frequency. By investigating this net phase-matching condition, one can measure spectral change in the refractive index which is responsible for the slow light effect based on stimulated Brillouin scattering. Due to the high sensitivity of the measurement, very small refractive index changes (on the order of 10-8) versus frequency detuning can be determined experimentally, which is the lowest index change reported so far.
