We demonstrate $\chi(3)$-based nonlinear interactions in silica solid and hollow resonators, consisting in third harmonic generation and Raman assisted TSFG in the visible and broadband hyper-parametric oscillation in forward and backward directions. Stimulated Brillouin Scattering is also demonstrated in forward and backward directions and the coexistance of nonlinear phenomena with optomechanical oscillations as well as the conditions for suppression of frequency generation in the presence of parametrical optomechanical oscillations.
