Design of signal router employing optical switching in MIM plasmonic waveguides

摘要

The all optical routing is novel approach for establishment of transparent information flow in optical networks. The diffraction limit of light is major factor which backseats the photonic components and mitigated by integrated all optical components. In this paper, an all-optical signal router with two optical inputs using nonlinear plasmonic Mach-Zehnder interferometer (MZI) is proposed. The nonlinearity in MZI structure is achieved by using nonlinear Kerr-material, which is also responsible for switching of optical signal across two output ports. The study of proposed device is carried out using finite-difference-time-domain (FDTD) method and verified using MATLAB.
