We propose a plasmon enhanced fluorescence microscopy technique below the quantum noise limit. This is achieved by exciting fluorescent molecules with photon number squeezed (PNS) light and using nanoparticles as an enhancer for overcoming the low absorption cross section. PNS light has an inherent sub-Poissonian photon distribution for which the variance Δn<⟨n⟩. PNS light has the added advantage of antibunching, which eliminates photobleaching due to higher order photon interactions. We anticipate that single molecule studies will benefit from such a radiation source.
