Abstract:

In this paper, a plasmonic filter made of a split ring, two U-shaped structures and two straight waveguides is designed and investigated. In the proposed structure, the split ring and U-shaped structures are situated between straight waveguides. Simulations are done based on FDTD method. Split ring, U-shaped structures and straight waveguides are made of air in the silver background. In the proposed structure, by altering the split angle, transmitted power and resonance wavelengths can be changed and tuned. The structure can confine light to sub-wavelength dimensions (on the order of nm) which makes it appropriate for optical integrated circuits. By adjusting the structural parameters, transmission powers up to 90% can be obtained.

1xN plasmonic power splitters based on metal-insulator-metal waveguides.

Novel plasmonic power splitters constructed from a rectangular ring resonator with direct-connected input and output waveguides are presented and numerically investigated. An analytical model and systematic approach for obtaining the appropriate design parameters are developed by designing an equivalent lumped circuit model for the transmission lines and applying it to plasmonic waveguides.

Plasmonic Adder/Subtractor Module Based on a Ring Resonator Filter

A four port network adder-subtractor module, for surface plasmon polariton (SPP) waves based on a ring resonator filter is proposed. The functionality of module is achieved by the phase difference manipulation of guided SPPs through different arms connected to the ring resonator. The module is designed using the concepts of a basic two-port device proposed in this paper. It is shown that two po...

A plasmonic modulator based on metal-insulator-metal waveguide with barium titanate core

We design a plasmonic modulator which can be utilized as a compact active device in photonic integrated circuits. The active material, barium titanate (BaTiO3), is sandwiched between metal plates and changes its refractive index under applied voltage. Some degree of switching of ferroelectric domains from the in-plane to out-of-plane orientation provides the change of the refractive index, whic...

Detuned Plasmonic Bragg Grating Sensor Based on a Defect Metal-Insulator-Metal Waveguide

A nanoscale Bragg grating reflector based on the defect metal-insulator-metal (MIM) waveguide is developed and numerically simulated by using the finite element method (FEM). The MIM-based structure promises a highly tunable broad stop-band in transmission spectra. The narrow transmission window is shown to appear in the previous stop-band by changing the certain geometrical parameters. The cen...

Achieving planar plasmonic subwavelength resolution using alternately arranged insulator-metal and insulator-insulator-metal composite structures

This work develops and analyzes a planar subwavelength device with the ability of one-dimensional resolution at visible frequencies that is based on alternately arranged insulator-metal (IM) and insulator-insulator-metal (IIM) composite structures. The mechanism for the proposed device to accomplish subwavelength resolution is elucidated by analyzing the dispersion relations of the IM-IIM compo...
