A Highly-Efficient and Compact Surface Plasmon Polaritons High-Pass Filter based on MIM waveguides

Abstract

This letter presents design and simulation results of a highly-efficient and compact plasmonic high-pass filter based on a MIM waveguide. Numerical results reveal that by tailoring structural parameters, desired cutoff wavelength can be chosen.

A Highly-Efficiency NIR Plasmonic Long-Wavelength Cut-Off Filter based on Stepped Impedance Resonators

“…In summary, a novel, highly compact, and tunable NIR long-wavelength cut-off filter based on SIRs is proposed and numerically investigated. Furthermore, compared to recent studies [8][9], not only does the proposed structure provides smaller footprint, but at the same time offers higher efficiency, which may find applications in image processing systems and in high-density PICs.…”
