Stimulated Brillouin scattering (SBS) of visible light in a small-core photonic crystal fiber (PCF) resonator of small external Q-factor, experimentally presents trains of subluminous and superluminous pulses presenting all the characteristics of dissipatif Brillouin solitons. Insertion of the acoustic dispersion, which may be significant in PCF, in the coherent SBS three-wave model modify the dissipative structures. For special pump wavelengths the acoustic dispersion response may be particularly strong and may lead to an enhanced Brillouin mirror.
