Paper Abstract

Coupled modes of surface plasmon polariton in two metal/dielectric interfaces are studied experimentally by using attenuated total reflection (ATR) method. Metal/dielectric interfaces are fabricated as metal gap waveguides on a high refractive index prism. ATR spectra are analyzed by mode analysis for the metal gap waveguide. A tapered metal gap waveguide is proposed as an effcient coupler from optical fibers to nano-optical circuits. FDTD simulations show adiabatic conversion of wavenumber of coupled surface plasmon polariton.
