“…3(a)) disappears when R=80nm. The above result suggests the exciton-plasmon coupling effect could be neglected when the interparticle distances longer than about 80nm for the other parameters set in this paper, which is quite different from the previous results [4][5][6][7][8][9][10], where it was found that there will be a single complete reflection peak when the frequency of the propagating plasmon is resonant with that of the bare exciton. However, our result shows that there could not be appeared a complete reflection peak even when sp    0 because of the plasmonic effect of the MNP on the SQD at the frequencies of the classic optical induced field different from 3eV.…”

By using the real-space method, switching of a single plasmon interacting with a hybrid nanosystem composed of a semiconductor quantum dot (SQD) and a metallic nanoparticle (MNP) coupled to one-dimensional surface plasmonic waveguide is investigated theoretically. We discussed that the dipole coupling between an exciton and a localized surface plasmon results in the formation of a hybrid exciton and the transmission and reflection of the propagating single plasmon could be controlled by changing the interparticle distance between the SQD and the MNP and the size of the nanoparticles. The controllable transport of the propagating single surface plasmon by such a nanosystem discussed here could find the significant potential in the design of next-generation quantum devices such as plasmonic switch, single photon transistor and nanolaser and quantum information.

“…Kim et al principally constructed a switch that can be used as a tristate gate. 52,53 By tuning and changing the number of equal transition frequencies of quantum dots coupled to one-dimensional SPP waveguide, the transmission and reflection of a single plasmon can be switched on or off (Figure 5a). Chang et al also developed a single photon transistor that can act as a non-linear two-photon switch for the SPPs propagating on an NW.…”

Nanoplasmonic waveguides: towards applications in integrated nanophotonic circuits

The properties of propagating surface plasmon polaritons (SPPs) along one-dimensional metal structures have been investigated for more than 10 years and are now well understood. Because of the high confinement of electromagnetic energy, propagating SPPs have been considered to represent one of the best potential ways to construct next-generation circuits that use light to overcome the speed limit of electronics. Many basic plasmonic components have already been developed. In this review, researches on plasmonic waveguides are reviewed from the perspective of plasmonic circuits. Several circuit components are constructed to demonstrate the basic function of an optical digital circuit. In the end of this review, a prototype for an SPP-based nanochip is proposed, and the problems associated with building such plasmonic circuits are discussed. A plasmonic chip that can be practically applied is expected to become available in the near future. Keywords: nanophotonics; plasmonic chip; plasmonic circuit; surface plasmons; waveguide INTRODUCTIONThe technologies of semiconductor integrated circuits and modern electronic integrated devices are rapidly approaching their fundamental limits in terms of both speed and data transmission rate (DTR).1 One of the promising solutions to these problems is using light rather than electrons in the functional processing components.2 However, the feasibility of fabricating nanoscale photonic devices may be limited because the diffraction limit of light is dominant when the size of a photonic device is close to or smaller than the wavelength of light in the material. Surface plasmon polaritons (SPPs), electromagnetic waves coupled to charge oscillation at the metal dielectric interface, can circumvent the diffraction limit and achieve localisation of electromagnetic energy in nanoscale regions that are considerably smaller than the wavelengths of light in the material. 3 The electromagnetic field perpendicular to the interface between metal and dielectric decays exponentially with distance from the metal surface while maintaining the long-range propagation of electromagnetic energy along the surface. This essential feature of SPPs can enable the fabrication of photonic components and optical signal processing devices at the sub-wavelength scale.Surface plasmons (SPs) include the localised type (localised surface plasmons, LSPs) and propagating type (propagating surface plasmon polaritons, PSPPs). For the purpose of optical signal transportation and nanophotonic circuits, only PSPPs will be considered in this review, and they are referred to as SPPs hereafter. Because of the unique properties of tightly confined SPPs on metal structures, various types of metallic nanostructures, such as nanoparticle chains, 4-7 thin metal films, 8 metal slits, 9 grooves, 10 chemically synthesised metal nanowires (NWs)

“…3a, the transmission spectra exhibit an oscillatory pattern with half of the wavelength of the propagating plasmon as a period in terms of spacing between From Fig. 2b, c, we also found that the order of the QDs can influence on the scattering of the incident plasmon, which is quite different with the case of a two-QD system [21,22]. Especially, we can construct a half-transmitting mirror with the three-QD system by controlling the transition frequencies of QDs and setting the spacing kL 1 as 1.37π, as shown in Fig.…”

“…Many theoretical [5][6][7][8][9][10][11][12][13][14][15] and experimental [16][17][18] works reported the photon scattering in different quantum systems. In the previous studies, the authors have mainly considered the scattering properties of a single photon interacting with one emitter and several emitters, and they mainly focus on the case where the quantum emitters are all equally spaced each other [19][20][21][22][23][24].…”

Scattering properties of a single plasmon interacting with three non-equally spaced two-level quantum dots (QDs) and a V-type three-level QD, coupled to 1D surface plasmonic waveguide, respectively, are investigated theoretically via the real-space approach. It is demonstrated that the transmission and reflection of a single plasmon can be switched on or off by controlling the detuning and changing the interparticle distances between the QDs. By controlling the transition frequencies and interparticle distances of QDs, one can construct a halftransmitting mirror with a three-QD system. We also showed that the transmission spectra of a single plasmon interacting with a two-level QD and a V-type three-level QD are quite the same as those with three two-level QDs when the spacing between the two-level QD and the Vtype three-level QD is equal to the spacing between twolevel QDs in the three two-level QD system.
