Abstract

We study Raman scattering in active media placed in proximity to different types of metal nanostructures, at wavelengths that display either Fabry–Perot or plasmonic resonances, or a combination of both. We use a semiclassical approach to derive equations of motion for Stokes and anti-Stokes fields that arise from quantum fluctuations.

Our calculations suggest that local field enhancement yields Stokes and anti-Stokes conversion efficiencies between 5 and 7 orders of magnitudes larger compared to cases without the metal nanostructure.

We also show that to first order in the linear susceptibility the local field correction induces a dynamic, intensity-dependent frequency detuning that at high intensities tends to quench Raman gain.
