Stimulated Brillouin Scattering by Dual Lasers Pumping in WGM Microcavities
Stimulated Brillouin scattering (SBS) is experimental investigated in several hundred microns in diameter microspheres with a little eccentricity by melting a fiber tip in a fusing splicer. Fourth order cascaded SBS at C-band (~1540 nm) with 27 mW can be achieved with the abundant and high Q modes i...
