Journal ArticleDOI
Plasmonic Refractive Index Sensor with High Figure of Merit Based on Concentric-Rings Resonator.
TL;DR: A plasmonic refractive index sensor based on metal-insulator-metal (MIM) waveguide coupled with concentric double rings resonator (CDRR) with high optical resolution with special cases of bio-sensing and triple rings is proposed and investigated numerically.
Journal ArticleDOI
Tunable band-stop plasmonic waveguide filter with symmetrical multiple-teeth-shaped structure
TL;DR: It is found that the bandgap width increases continuously with the increasing number of teeth, and may have meaningful applications in ultra-fine spectrum analysis and high-density nanoplasmonic integration circuits.
Journal ArticleDOI
Ultra-compact broadband polarization beam splitter with strong expansibility
TL;DR: Based on the traditional directional coupler, a scheme to design on-chip polarization beam splitters using an inverse design method was proposed in this article, where the coupling area of the designed devices are only 0.48 μm×6.4
Journal ArticleDOI
Near-infrared tunable metalens based on phase change material Ge 2 Se 2 Te 5
TL;DR: This work designs a near-infrared tunable metalens treating phase change materials as the meta-atoms which makes the tunableMetalens become more compact and may bring some good opportunities for the revolution of the next generation tunable integrated optics.
Journal ArticleDOI
All-optical multi-channel switching at telecommunication wavelengths based on tunable plasmon-induced transparency
TL;DR: In this paper, an all-optical plasmon-induced transparency (PIT)-based multi-channel switching based on the metal-insulator-metal (MIM) PLASmonic waveguide device with small footprint is proposed.
