“…It is necessary to mention here that optical properties of the aligned Ag nanorod arrays are anisotropic and they strongly depend on polarization of incident angle because when light hits aligned nanorods, the oscillation of the electric field induces the longitudinal plasmon mode along the nanorods and the transverse plasmon mode perpendicular to the nanorods [8,17].…”

This study presents an experimental evaluation of the light-matter interactions in silver nanorod arrays of various lengths fabricated by electron-beam physical vapor deposition. The reflectance of nanorod arrays is found to decrease with increasing nanorod length, reaches to a minimum and then again increases with increasing length. Since nanorod arrays are subwavelength structures, the decrease in reflectance is primarily due to surface plasmon resonance. At the tip of the nanorods, the light excites the surface plasmons, which propagate along the conductor-dielectric interface. Hence, longer and consequently higher surface area nanorod arrays provide more dielectric-conductor interface for light to couple with the surface plasmons and more surface to scatter resulting in lower reflectance.

“…Compared to conventional optical microcavities, the plasmonic structure has the ability of subwavelength optical field confinement [ 18 ], causing a sharp suppression in its V mode as well as an enhanced and localized electric field, further increasing the value of / [ 19 ]. For example, the plasmonic gold dimer [ 20 ] and silver nanorod [ 21 ] are used to construct microcavities. However, due to the constant collision of free electrons and atoms (ions) in metals, the surface plasmon mode has a high intrinsic loss and low value, which limits further investigation and their potential applications.…”

Entanglement generation by strong coupling between surface lattice resonance and exciton in an Al nanoarray-coated WS2 quantum emitter

Strong light–matter interaction plays a central role in realizing quantum photonic technologies. The entanglement state, which results from the hybridization of excitons and cavity photons, forms the foundation of quantum information science. In this work, an entanglement state is achieved by manipulating the mode coupling between surface lattice resonance and quantum emitter into the strong coupling regime. At the same time, a Rabi splitting of 40 meV is observed. A full quantum model based on the Heisenberg picture is used to describe this unclassical phenomenon, and it perfectly explains the interaction and dissipation process. In addition, the observed concurrency degree of the entanglement state is 0.5, presenting the quantum nonlocality. This work effectively contributes to the understanding of nonclassical quantum effects arising from strong coupling and will intrigue more interesting potential applications in quantum optics.

“…Strong coupling between a plasmonic cavity and a molecule not only attracts interest in the fundamental study of quantum electrodynamic phenomenon, but also has a bright prospect in quantum information processing [21–23]. Plasmonic cavities, which can significantly enhance the strength of the light-matter interaction, are an appropriate candidate to achieve the strong coupling at room temperature [24–26]. However, a single molecule coupling with a plasmonic cavity is a huge challenge in both theory and experiment, which is difficult to manipulate the position of the molecule in the coupling system.…”

Strong Coupling between a Quasi-single Molecule and a Plasmonic Cavity in the Trapping System

et al. 2019

We theoretically investigate the strong coupling phenomenon between a quasi-single molecule and a plasmonic cavity based on the blue-detuned trapping system. The trapping system is made up of a metallic nanohole array. A finite-difference time-domain method is employed to simulate the system, and the molecule is treated as a dipole in simulations. By calculating the electromagnetic field distributions, we obtain the best position for trapping a molecule, and we get the strong coupling phenomenon that there are two splitting peaks in the transmission spectrum when the molecule is trapped in the structure, while only one peak is observed in the one without the molecule. We also find that only when the molecule polarization parallels to the incident light wave vector can we observe a strong coupling phenomenon.
