“…The mean-field chromophore interaction is included through a fieldand positiondependent dielectric function with gain saturation. However, more complex cooperative effects 141,142 have been intentionally omitted, as they should be smeared out by strong dephasing and random dipole orientations. A recent study 143 has confirmed that for tens of thousands of randomly oriented molecules, the ensemble-averaged dipole-dipole coupling should vanish, and the resonant mode should remain unaffected.…”

Ten years ago, three teams experimentally demonstrated the first spasers, or plasmonic nanolasers, after the spaser concept was first proposed theoretically in 2003. An overview of the significant progress achieved over the last 10 years is presented here, together with the original context of and motivations for this research. After a general introduction, we first summarize the fundamental properties of spasers and discuss the major motivations that led to the first demonstrations of spasers and nanolasers. This is followed by an overview of crucial technological progress, including lasing threshold reduction, dynamic modulation, room-temperature operation, electrical injection, the control and improvement of spasers, the array operation of spasers, and selected applications of single-particle spasers. Research prospects are presented in relation to several directions of development, including further miniaturization, the relationship with Bose-Einstein condensation, novel spaser-based interconnects, and other features of spasers and plasmonic lasers that have yet to be realized or challenges that are still to be overcome.

“…To accomplish this goal, we developed a quasi-classical approach to describe nonlinear plasmon-exciton interactions in multi-photon schemes [12], and also demonstrated the possibility for the realization of strong coupling conditions in a high-LDOS system. In addition, we used analytical and numerical methods to analyze the stability of the steady-state regimes of the waveguide transmittance.…”

“…Note that interband conductivity does not influence the curves in Figure 3. On the other hand, Figure 4 shows the curves calculated in accordance with Equation (12) in the regime of weak SPP-graphene coupling for wavelength 2.56 µm. They are almost identical with the numerical solution of Equation (10), but the contribution of interband conductivity increases at this wavelength.…”

All-Plasmonic Switching Effect in the Graphene Nanostructures Containing Quantum Emitters

et al. 2020

Nonlinear plasmonic effects in perspective 2D materials containing low-dimensional quantum emitters can be a basis of a novel technological platform for the fabrication of fast all-plasmonic triggers, transistors, and sensors. This article considers the conditions for achieving a strong coupling between the surface plasmon–polariton (SPP) and quantum emitter taking into account the modification of local density of optical states in graphene waveguide. In the condition of strong coupling, nonlinear interaction between two SPP modes propagating along the graphene waveguide integrated with a stub nanoresonator loaded with core–shell semiconductor nanowires (NWs) was investigated. Using the 2D full-wave electromagnetic simulation, we studied the different transmittance regimes of the stub with NW for both the strong pump SPP and weak signal SPP tuned to interband and intraband transition in NW, respectively. We solved the practical problem of parameters optimization of graphene waveguide and semiconductor nanostructures and found such a regime of NW–SPP interaction that corresponds to the destructive interference with the signal SPP transmittance through the stub less than 7 % in the case for pump SPP to be turned off. In contrast, the turning on the pump SPP leads to a transition to constructive interference in the stub and enhancement of signal SPP transmittance to 93 % . In our model, the effect of plasmonic switching occurs with a rate of 50 GHz at wavelength 8 µ m for signal SPP localized inside 20 nm graphene stub loaded with core–shell InAs/ZnS NW.

“…The threshold conditions under which QD concentration proves to be sufficient for the development of collective effects in a waveguide spaser even taking into account fast decay of the SPP in the metal were determined. The comparison of different regimes of SPP pulse formation in a metal/dielectric interface was carried out by use of simulation (1). The optimum values of n , which make it possible to completely compensate the relaxation processes in QD (Fig.…”

The method of surface plasmon-polariton pulses generation via cooperative effects in a waveguide spaser

2017

View full text Add to dashboard Cite

Cooperative effects arising under conditions of a 0-D model for a dense ensemble of semiconductor quantum dots located in a dielectric layer near a flat metal surface are considered. The threshold conditions of the effect are determined and the values of the complex refractive index of the dielectric are chosen, which make it possible to increase the efficiency of the formation of surface plasmon-polariton (SPP) pulses.In this paper we consider the problem of SPP pulse generation during the collective exciton decay of excited quantum dots (QDs) with concentration N placed in a dielectric layer near a metal surface (Fig. 1a). The QD size is determined by condition of plasmon-exciton resonance (Fig. 1b), and the QD concentration corresponds to compensation of losses at the considering scales. The development dynamics of collective effects is described by selfconsistent equations for population imbalance 21 n , QD polarization 21  , and Rabi frequency 0  :
