An Extremely Miniaturized and Highly-Efficient High-Pass Wavelength Plasmonic Filter at Near-Infrared

Abstract

This letter describes design and numerical simulation of an extremely-compact and efficient high-pass plasmonic filter based on MIM waveguides. Numerical results shown that by tuning structural parameters, desired cut-off wavelengths can be chosen. OCIS codes: (240.6680) Surface plasmon; (130.7408) Wavelength filtering devices.
