Abstract:   (200 Views)
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.
