Few Photons Probe Third-Order Nonlinear Properties of Nanomaterials in a Plasmonic Nanocavity
Quantification of nonlinear optical properties is important for nano-optical devices, yet such measurements remain challenging at the single-particle level. Here, we harness enhanced optical fields inside a plasmonic nanocavity to mediate efficient nonlinear interactions with an individual particle, down to two photons per pulse.
