- Abstract: A single photon in a strongly nonlinear cavity is able to block the
transmission of the second photon, thereby converting incident coherent light
into anti-bunched light, which is known as photon blockade effect. On the other
hand, photon anti-pairing, where only the entry of two photons is blocked and
the emission of bunches of three or more photons is allowed, is based on an
unconventional photon blockade mechanism due to destructive interference of two
distinct excitation pathways. We propose quantum plexcitonic systems with
moderate nonlinearity to generate both anti-bunched and anti-paired photons.
The proposed plexitonic systems benefit from subwavelength field localizations
that make quantum emitters spatially distinguishable, thus enabling a
reconfigurable photon source between anti-bunched and anti-paired states via
tailoring the energy bands. For a realistic nanoprism plexitonic system, two
schemes of reconfiguration are suggested: (i) the chemical means by partially
changing the type of the emitters; or (ii) the optical approach by rotating the
polarization angle of the incident light to tune the coupling rate of the
emitters. These results pave the way to realize reconfigurable nonclassical
photon sources in a simple quantum plexcitonic platform with readily accessible
experimental conditions.
