All-optical control of photon statistics with hybrid quantum plasmonic system

We propose an all-optical scheme to control the photon statistics using hybrid quantum plasmonic system. With the aid of dressed states, it is shown that the photon correlation of signal field can be continuously modulated from bunching to antibunching under the control of a pump field. Apart from the exact multimode model, we identify the roles of multimode coupling and quantum interference between probability amplitudes, peculiar to the studied system, through a single-mode model and an analytical treatment. Different from the cavity quantum electrodynamics methods, the proposed scheme works well in the bad cavity limit. These findings suggested that this hybrid system provides a feasible nanophotonic platform for active modulation of photon correlation and for future quantum devices.
