Optical Ultra-Wideband Nano-Plasmonic Bandpass Filter Based on Gap-Coupled Square Ring Resonators
In this work, an ultra-wideband (UWB) optical bandpass filter (BPF) based on nanoplasmonic structure is designed and thoroughly analyzed. The proposed BPF structure encompasses asymmetric metal-insulator-metal (MIM) slot waveguide that incorporates a gap-coupled series and parallel square ring reson...
