The Study Of Quantum Effects In Surface Plasmon Polaritons

Surface plasmon polaritons (SPPs) is an electromagnetic surface wave which generated by oscillation of electrons in metal surfaces propagating in the form of electromagnetic waves along the interface between the metal and dielectric median. After years of development, such a large number of experiments show that SPPs have quantum features. Therefore, in this paper, we will study the quantum effects in surface plasmon polaritons, which have important significance for quantum information processing and communications.The paper consists of six chapters. The first chapter mainly reviews the history and status progress of applications in surface plasmon polaritons. The second chapter describes the basic electromagnetic theories and features, such as excitation modes and four characteristic length parameters of surface plasmon polaritons. In chapter three, we fully describes the experiments and theoretical progress of quantum features of SPPs. Firstly we analysis the transmission of squeezed state surface plasmons in waveguide by heat reservoir theory of quantum optics, then we calculate the loss coefficient of waveguide, which is used to explain Huck’s experiment. In chapter four, the quantization method of surface plasmons polaritons has been studied. In chapter five, we analysis the formation of surface plasmons spatial solitons at the interface between metal and Kerr dielectric, then calculate the nonlinear Schrodinger equation with losses of soliton transmission by Hirota’s bilinear method. In the last chapter, the research of this paper are summarized. We raise expectations in later study of quantum effects in surface plasmon polaritons...
