Semiclassical dynamics of the lemniscate ordered emitters enhanced by plasmon-polaritons in nanorings

Abstract

The semiclassical dynamics of optical nanoemitters (NEs) arranged in the shape of a Bernoulli lemniscate (LB), enhanced by plasmon–polaritons (PPs) in a lattice of conducting nanorings (NRs), are investigated. The coupling of PP and NE is mediated by a common optical field and NE with a finite lifetime of pumping are considered. Using the FDTD approach, it is found that the field structure and the NE dynamics significantly depend on the plasma frequency of the NR. If the intersection point of the LB branches (the region of high NE density) is located inside the NR gaps, a significant increase in the laser field strength and quantum cross-correlations in the NE subsystem occurs. This effect may be exploited to create new types of emitting devices using dispersed nano-objects in modern nanoelectronics.
