A NOVEL DUAL-BAND BAND-PASS FILTER USING PLASMONIC SQUARE RING RESONATOR

摘要

We propose a plasmonic Metal-Insulator-Metal (MIM) waveguide based on a new ring resonator Band-Pass Filter (BPF) with tunable band-pass bandwidth. We use very easy techniques for analyzing the resonant frequencies and transmission coefficients. The band-pass filter operates at optical wavelengths in between O & L bands. To design band-pass filters, stepped-impedance stubs with open lengths are connected with the ring to acquire the tunable bandwidth. A full wave simulation software tool is used in the design of the band-pass filter. The filter has wide applications in high density Photonic Integrated Circuits (PICs).
