Experimental and theoretical results of spontaneous Brillouin scattering (SpBS) in solid silica microfibers have been demonstrated1,2. Surface acoustic waves and Brillouin scattering self-cancellation were found and discussed in the two papers1,2. In our paper, we investigated the stimulated Brillouin scattering (SBS) process in solid and hollow microfibers. Our conclusion was that SBS can be suppressed in a solid microfiber and even be completely cancelled in a hollow microfiber. Our theoretical model did not include SpBS which originates from the acoustic waves caused by Brownian motion (thermal motion), thus self-cancellation effect of SpBS in solid microfiber was not demonstrated in our work.
