Plasmon Enhanced Symmetric Mode Generation in Metal-Insulator-Metal Structure with Kerr Nonlinear Effect

چکیده
A time domain simulation algorithm for the investigation of propagation properties of nonlinear Surface-PlasmonPolaritons (SPP) mode through gallium lanthanum sulphide (GLS) layer in Ag-GLS-Ag waveguide is presented. GLS, a semiconducting chalcogenide glass is known as ultrafast nonlinear device due to their high material non-linearity with strong confinement and dispersion. The time domain simulation algorithm is developed using the Finite Difference Time Domain (FDTD) method. The frequency-dependent dispersion relations as well as third-order non-linearity of GLS glass are modeled using the general polarization algorithm incorporated in the auxiliary differential equation (ADE) technique considering the Kerr nonlinear effect. The dynamics of the whole system is simulated and the effect on SPP propagation is also studied. General Terms Finite Difference Time Domain (FDTD), Auxiliary differential equation (ADE), Kerr nonlinear effect.

Nanofocusing in a metal - insulator - metal gap plasmon waveguide with a 3 - dimensional linear
An Au-SiO2-Au (metal-insulator-metal; MIM) surface-plasmon-polariton (SPP) guide is schematically presented in Fig. S1a. As the name “MIM” implies, a structural symmetry exists with respect to the mirror plane that cuts through the center of the SiO2 layer and is parallel to the x–y plane. As a result, supported SPP modes in the guide can be classified into two major types, each with its own di...

A scheme for the excitation of slow surface plasmon pulses using photonic interband transition in a metal-insulator-metal (MIM) waveguide is proposed. An investigation the mode transition behavior inside the binary grating confirmed that the proposed concept can be understood in terms of the coupling of symmetric and anti-symmetric plasmonic modes.
