Recent advances on Surface Enhanced Raman Scattering (SERS) have led to a delicate control of the coupling between extremely-confined plasmonic resonances supported by metallic structures and the vibrational states of molecules. As a consequence, experiments have started to emerge that cannot be easily explained using standard models based on the classical enhancement of the plasmonic fields near...
Plasmonic cavities are suitable platforms for studying the interaction of light and matter at the nanoscale. It has been demonstrated that plasmonic cavities are able to squeeze light into nanometer-sized volumes and thus open novel possibilities for studying the interaction of single molecules with light. For example, it has been recently shown that off-resonance Surface-Enhanced Raman Spectroscopy...
The development of the Raman gas-filled hollow core photonic crystal fibers allow to exacerbate the light-matter interaction with extremely high efficiency. Among the nonlinear optical effect that were extensively explored we count stimulated Raman scattering, with demonstrations like over 5-octaves wide Raman comb using H2-filled inhibited coupling guiding HC-PCF pumped with a picosecond pulsed laser...
