Photon blockade through microcavity-engineered plasmonic resonances

ABSTRACT

We propose a scheme for experimental implementation of a strong photon blockade with a microcavity-engineered plasmonic resonances. For this aim, we propose to engineer the environment of localized-surface plasmon resonances by placing metallic nanoparticles (MNPs) in optical microcavities. In the paper, we analyse normalized second-order correlation function of the system. The strong antibunching is found by analytic calculations under the optimal conditions, which coincide well with the numerical results. We also examine the statistical properties of the photons by tuning the parameter under the optimal condition. And the impact of the average number of photons is briefly discussed. Importantly, our results provide a promising method for the study of quantum information processing.
