A tunable nanocube-on-mirror Fabry-Pérot cavity for sideband-resolved molecular optomechanics
We demonstrate a tuneable nanocube-on-mirror Fabry-Perot cavity that combines the record breaking plasmonic confinement of the nanocube-on-mirror (NCoM) system with the high quality factors and tuneability of microcavity systems. We demonstrate selective addressing of individual molecular vibrational lines with robust SERS enhancements on par with those of the seminal NCoM system, reaching sideband resolved SERS at Q/V values above 1 million inverse cubic wavelengths. We envision this as a platform for sideband-resolved molecular optomechanics, polariton chemistry and vibrational strong coupling.
