Abstract

Surface-enhanced coherent Raman scattering (SE-CRS) promises high signal rates at low molecular concentrations, down to the single molecule limit. Although single molecule SE-CRS has been reached, experiments thus far have been affected by heating effects at plasmonic substrates, which has stifled progress. We discuss a SE-CRS strategy based on dielectric nano-antennas of high index materials, which feature low losses and are thermally more robust than nano-structured metals. We demonstrate molecular SE-CRS signals using Si-based antennas and show improved repeatability, controllability and signal stability.
