“…In addition, surface plasmons (SPs) have attracted interest due to their unique property to confine a great amount of electromagnetic energy at subwavelength scales and for providing strong coupling of light to emitter systems. Enhanced emission rate due to SP excitations in a variety of metal nanostructures such as uniform planar microcavities, metal nanoparticles and metal nanowires, have been the subject of many theoretical and experimental investigations [4,5,6,7].…”

Abstract. We present a theoretical study of the spontaneous emission of a line dipole source embedded in a graphene-coated subwavelength wire of arbitrary shape. The modification of the emission and the radiation efficiencies are calculated by means of a rigorous electromagnetic method based on Green's second identity. Enhancement of these efficiencies is observed when the emission frequency coincides with one of the plasmonic resonance frequencies of the wire. The relevance of the dipole emitter position and the dipole moment orientation are evaluated. We present calculations of the near-field distribution for different frequencies which reveal the multipolar order of the plasmonic resonances.

“…[2][3][4] It has also been found other effects of SPPs, including field enhancement [6][7][8] , and influence on lifetime of emitters close to the SPPs . 9,10 In various plasmonic structures, cylindrical metallic nanowire [11][12][13][14][15][16] as a symmetric plasmonic structure has been widely studied for the applications of the optical waveguide and the scanning near-field optical microscopy (SNOM). In order to understand the physical properties of SPPs in those structures, it is important to get the dispersion relations of the frequency and wave vector of the SPPs, which determine the basic properties of the SPPs.…”

“…11,14 The SPPs dispersion relations of plasmonic structures are complex when the metal Ohmic losses are introduced. 15,17,18 There exist two types of solutions to the complex dispersion relations. One solution specifies a complex frequency as a function of a real wave vector, noted as complex −ω for convenience.…”

Analytical solutions to zeroth-order dispersion relations of a cylindrical metallic nanowire near the backbending point

Zeroth-order complex dispersion relations of a cylindrical metallic nanowire have been solved out analytically with approximate methods. The analytical solutions are valid for the sections of the dispersion relations whose frequencies are close to the Surface Plasmon frequency. The back bending of the Surface PlasmonPolaritons(SPPs) can be well described by the analytical solutions, confirming that the back bending is originated from the metal Ohmic loss. The utility of the back bending point in the dispersion relation for the measurement of the metallic Ohmic loss has also been suggested.

The reflection and transmission characteristics of a system composed of two whispering‐gallery mode (WGM) resonators are explored. Each resonator contains a Zeeman split quantum dot and side‐couples to an optical fiber. The results indicate that the unidirectional reflectionlessness and transmissionlessness can be achieved by adjusting the coupling strength between the resonators and the optical fiber, as well as the transition rate between the counter‐propagating modes within the WGM resonators. Besides, a one‐to‐one correspondence is set up between the resonance frequencies of quantum dots' energy levels and the positions of reflectionlessness (transmissionlessness) peaks when phase shift between two WGM resonators is π. This research provides the valuable insights for the development of quantum optical devices such as isolators, circulators, and routers.
