A quantized form of Surface Plasmon Polariton (SPP) modes propagating on the metal thin film is provided, which is based on the Green's tensor method. Since the media will be considered lossy and dispersive, the amplification and attenuation of the SPP modes in various dielectric media, by applying different field frequencies, can be studied. We will also illustrate the difference between behavior of coherent and squeezed SPP modes in the amplifying media. arXiv:1507.04108v1 [quant-ph] 15 Jul 2015
The detection and characterization of a non-classical-squeezed state of light, by using two different schemes, will be presented . In the first one, in an one-dimensional cavity with moving mirror (non-stationary Casimir effect) in the principal mode, we study the photon creation rate for two modes (squeezed and coherent state) of driving field. Since the cavity with moving mirror (similar to an optomechanical system) can be considered analogue to a Kerr-like medium, so that in the second scheme, the probability amplitude for multi-photon absorption in a nonlinear (Kerr) medium will be quantum mechanically calculated. It is shown that because of presence of nonlinear effects, the responses of these two systems to the squeezed versus coherent state are considerably distinguishable. The drastic difference between the results of these two states of light can be viewed as a proposal for detecting of non-classical states.
Quantum surface plasmon polaritons (SPPs) are a growing research area with many unknown phenomena. In this paper, the behavior of squeezed SPP modes on a metal slab is assessed. To begin with, a quantized form of the SPP modes propagating on the metal thin film based on Green’s tensor method is provided. Since the squeezing properties of the SPP modes are indeed transferred from incident photons, in the next step, different aspects of this phenomenon are studied. Obtaining an important direct relation between incident photons’ properties and SPP modes will allow for the effective factors on this phenomenon to be explored. Although the initial quantum properties will be changed or lost during the photon–surface plasmon interaction, it will be shown that some factors can improve the transfer process. Finally, the squeezing transfer from incident photons to the SPP modes and effective factors on it as a full quantum phenomenon will be investigated.
