“…The presented optoplasmonic system based on graphene and quantum dots can be a basis for the development of a novel technological QD-graphene platform for near-field sensing, [54] converters of far-field into near-field, and its applications. In particular, graphene has short response times and can be used as a unique 2D material for creating ultrafast optoplasmonic converters and switches [17,55] owing to graphene record values of electron mobility. At the same time, the satisfying of strong coupling conditions for individual QDs in array placed above the graphene is able to provide maximum energy efficiency of light into the nearfield conversion, as well as to realize switching with the generated power SPP flow.…”

“…One possible solution to these problems is the use of dissipative plasmonic systems with optical pumping and a special kind of resonator based on advanced 2D materials and loaded with semiconductor QDs. [ 17 ] At the same time, to maintain strong coupling conditions for a long time and observe the stable regime of SPP propagation, it is necessary to provide control over the competitive processes of gain and losses in such systems. A simple two‐level scheme of emitter excitation is not suitable for these purposes since it does not allow the control of population imbalance and polarization for the signal field transition.…”

Collective near‐field effects in perspective 2D materials containing semiconductor quantum emitters can be used to design novel devices for light manipulation on the nanoscale. The present paper considers an energy conversion from the pump laser field to the surface plasmon polaritons (SPPs) on the base of the hybrid optoplasmonic multi‐level scheme of near‐resonant interaction with semiconductor quantum dots (QDs) placed in the proximity of a graphene surface. Using numerical simulations and semiclassical approach for the light–matter interaction, it is shown that maximum efficiency of SPP generation is achieved in strong coupling conditions for a stationary regime of SPP‐QD interaction. Besides, the conditions for observation of SPP collective resonances in an ordered array of optically excited QDs placed above graphene are determined. Finally, the use of the constructive SPP interference regime in a meta‐layer of QDs above graphene for efficient near‐field amplification and subwavelength light concentration is proposed and discussed.

“…This selectivity allows for Boolean algebra [192], i.e., logical gates, and thus for optical computing with highly integrable and CMOS (Complementary Metal Oxide Semiconductor)-compatible devices [193][194][195][196]. Nonlinear optical phenomena, on the other hand, have also been recently demonstrated to be useful for plasmonic-based switching applications [197]. Of particular importance, symmetry-breaking features of plasmonic nanowires can also be used for polarization beam splitting, switching, and routing of light fields [198,199].…”

Plasmonic materials, when properly illuminated with visible or near-infrared wavelengths, exhibit unique and interesting features that can be exploited for tailoring and tuning the light radiation and propagation properties at nanoscale dimensions. A variety of plasmonic heterostructures have been demonstrated for optical-signal filtering, transmission, detection, transportation, and modulation. In this review, state-of-the-art plasmonic structures used for telecommunications applications are summarized. In doing so, we discuss their distinctive roles on multiple approaches including beam steering, guiding, filtering, modulation, switching, and detection, which are all of prime importance for the development of the sixth generation (6G) cellular networks.

Controllable Excitation of Surface Plasmon Polaritons in Graphene‐Based Semiconductor Quantum Dot Waveguides

The research aim of this study is the development of a theoretical semiclassical model of the controllable excitation and propagation of surface plasmon polaritons (SPPs) in planar graphene waveguides by the application of external voltage. The model is based on the numerical solution of the SPP's dispersion equation formulated for a system including two coupled graphene sheets with embedded quantum dots. Using the developed model, the different near-field patterns realized in the waveguides depending on the quantum dots' ordering and an external voltage applied independently to each graphene sheet with additional gold electrodes are numerically investigated. The obtained results show that the application of external voltage can locally change the chemical potential of graphene and, thereby, lead to controllable excitation of SPPs in the corresponding graphene waveguide. Furthermore, we revealed that the propagation direction of the excited SPPs is determined by the geometrical configurations of the gold electrodes that provide the required SPP routing. The investigated system offers new opportunities for near-field energy transport and concentration, which can be applied to develop ultra-compact photonic devices.
