Nonlinear optics at nanoscale is a recent fascinating research field. Among the numerous nonlinear optics phenomena, due to its significant implications from both fundamental and applicative point of view, stimulated Raman scattering is one of the most interesting. In this paper, the observations of stimulated Raman scattering in silicon nano-particles, at the wavelengths of interest for telecommunications,...

In this paper, experimental investigations of stimulated Raman scattering in silicon quantum dots and nanocomposites based Si-materials are reported. Two Raman amplifiers are realized and amplifications due to stimulated Raman scattering are measured. For both of them, a significant enhancement of Raman gain and a significant reduction in threshold power are demonstrated. Our findings indicate that...
