Surface plasmon mode analysis of nanoscale metallic rectangular waveguide

Spoof surface plasmon waveguide forces.

Spoof surface plasmons (SP) are SP-like waves that propagate along metal surfaces with deeply sub-wavelength corrugations and whose dispersive properties are determined primarily by the corrugation dimensions. Two parallel corrugated surfaces separated by a sub-wavelength dielectric gap create a "spoof" analog of the plasmonic metal-insulator-metal waveguides, dubbed a "spoof-insulator-spoof" (...

Characterizing ultrathin and thick organic layers by surface plasmon resonance three-wavelength and waveguide mode analysis.

A three-wavelength angular-scanning surface plasmon resonance based analysis has been utilized for characterizing optical properties of organic nanometer-thick layers with a wide range of thicknesses. The thickness and refractive index were determined for sample layers with thicknesses ranging from subnanometer to hundreds of nanometers. The analysis approach allows for simultaneous determinati...

Green’s function analysis of an ideal hard surface rectangular waveguide

[1] Green’s function analysis of an ideal hard surface rectangular waveguide is proposed for characterization of the modal spectrum of the structure. A decomposition of the hard surface waveguide into perfect electric conductor and perfect magnetic conductor waveguides allows the representation of dyadic Green’s function as a superposition of transverse magnetic (TM) and transverse electric (TE...

Analysis of v-groove surface plasmon polarition waveguide

We proposed the dielectric filling in a vgroove on GaAs wafer. In order to fabricate easily, the channel plasmon polaritons waveguide is proposed and analyzed, compared to conventional optical waveguide based on multi-epitaxial layer. The propagation loss is analyzed using 3-dimensional finite-difference time-domain method. We obtained the propagation loss of 1.02 dB / 30 μm.
