Cavity resonant enhanced Stimulated Raman Scattering, Four Wave Mixing and broadband hyper-parametric oscillation in silica microbubble whispering gallery mode resonators in forward and backward directions are reported in this letter. We show that microbubbles can operate not only in a highly ideal two-photon emission regime but also generate combs, both natively and multi mode spaced. The nonlinear process is phase matched due to the interaction of different mode families of the resonator

Abstract
Cavity resonant enhanced Stimulated Raman Scattering, Four Wave Mixing and broadband hyper-parametric oscillation in silica microbubble whispering gallery mode resonators in forward and backward directions are reported in this letter. We show that microbubbles can operate not only in a highly ideal two-photon emission regime but also generate combs, both natively and multi mode spaced. The nonlinear process is phase matched due to the interaction of different mode families of the resonatorFile in questo prodotto:
