“…For example, the purple curve in the plot shows subluminal propagation while the green and blue curves demonstarte superluminal light propagation. As can be seen, the rotation of light polarisation states in superluminal and subluminal regimes occur opposite and along medium motion, respectively, which are consistent with previous investigations [21,23,24,28,29,31]. In other words, based on signs of photon drag against translational and rotational velocity of medium, one can determine whether light propagation is subluminal or superluminal.…”

Controlling the basic properties of light such as polarization, angular momentum, and speed through various optical media leads to interesting phenomena in various fields such as quantum optics, photonics, plasmonics, and quantum information technology. Few of the phenomenon include, for instance, light storage, ultra-slow and ultra-fast propagation, optical transparency, and quantum entanglement via quantum coherence or superposition. The understanding of these phenomenon of milestone implications paved the way for the invention of novel classical and quantum technology. In this article, we present detailed theoretical and numerical demonstration on the dispersion-dependent phenomenon of slow and fast light, optically induced transparency, and photon drag. For this, we employ a three-level scheme of an ensemble of GaAs\AlGaAs double quantum dot molecule in cascade configuration. In particular, by tuning the medium dispersion we predict interesting interplay between ultra-slow and ultra-fast light propagation with vanishing, infinite, ultra-positive and ultra-negative group velocities, and optical-assisted quantum transparency. The quantum coherence of the dressed states modifies considerably the optical properties of the system in view of dispersion, absorption, electron energy loss, transmission, and photon drag. An interesting interplay between ultra-slow to ultra-fast propagation is found by tuning various optical parameters. The calculated superluminal value of group velocity is ±6×10^11 m/s. We also predict light propagation at vanishing and infinite group velocity. The calculated light drag is ±6×10^(-6) rad/m.

“…Recently, light dragging in view of plasmons has been reported in bulk graphene [25,26]. More recently, light drag in view of photon and surface plasmons has been investigated in quantum dots (QDs), QD molecules (QDMs), dots-metal, and dots-nanoparticle plasmonic interfaces [27][28][29][30][31][32].…”

We present a novel methodology for enhancing superluminal surface plasmon polaritons (SPPs) propagations within a hybrid nanostructure configuration consisting of gold (Au) metal and chiral quantum dots (CQDs) medium. The arrangement of CQDs and metal hybrid nanostructures enables the production of surface plasmon polaritons (SPPs) when exposed to incident light. Theresonances of SPPs within a hybrid nanostructure are determined through analytical calculations using Maxwell's equations underspecified boundary conditions, while the dynamics of the CQDs system are calculated using the density matrix approach. It isdemonstrated that the propagation of SPPs is significantly influenced by both right-circularly polarized (RCP) andleft-circularly polarized surface plasmon polaritons. Additionally, we investigate the enhancement of superluminal SPPspropagation by varying the electron tunneling strength and the intensity of the control field within the hybrid system. Thecharacteristics of RCP and LCP surface plasmon polaritons have been investigated, indicating a large negative group index andadvancement in time. The observation of a large negative group index and advancement in time provides strong evidence forenhanced superluminal SPPs propagation within the proposed hybrid nanostructure. The results have potential applications in thefields of optical information processing, temporal cloaking, quantum communication, and the advancement of computer chip speed.

“…In this case, propagating modes gain more strength due to the interference of phase-locked SPP modes, which amplifies the field amplitude at 715 nm in comparison to LSP (583 nm). The dip in the plasmon spectra occurs due to the strong hybridization of the LSP and SPP modes near the hole edge and the metal surface, which gives rise to plasmon-induced transparency at a particular frequency [39,40]. Furthermore, the nanoscale distance between the holes results in path interference of radiative modes that are scattered from the hole and the higher multipole modes (non-radiative) at the edge of the circular cavity, respectively [41].…”

Understanding the ultrafast processes at their natural-time scale is crucial for controlling and manipulating nanoscale optoelectronic devices under light-matter interaction. Here, we demonstrate that ultrafast plasmon resonances, attributed to the phenomenon of Extraordinary Optical Transmission (EOT), can be significantly modified by tuning the spectral and temporal properties of the ultrashort light pulse. In this scheme, all-optical active tuning governs spatial and temporal enhancement of plasmon oscillations in the EOT system without device customization. We analyze the spectral and temporal evolution of the system through two approaches. First, we develop a theoretical framework based on the coupled harmonic oscillator model, which analytically describes the dynamics of plasmon modes in the coupled and uncoupled state. Later, we compare the evolution of the system under continuous wave and pulsed illumination. Further, we discuss time-resolved spectral and spatial dynamics of plasmon modes through 3D-FDTD simulation method and wavelet transform. Our results show that optical tuning of oscillation time, intensity, and spectral properties of propagating and localized plasmon modes yields a 3-fold enhancement in the EOT signal. The active tuning of the EOT sensor through ultrashort light pulses pave the way for the development of on-chip photonic devices employing high-resolution imaging and sensing of abundant atomic and molecular systems.
