摘要

We have theoretically investigated a plasmonic metal-dielectric-metal (MDM) resonant system with water-based dielectric, which allow easy implementation of up to eight Fano resonant channels. The reported plasmonic MDM system is composed by an end-coupled square ring and three reversed L-shape cavities, which can support bright modes or dark modes that will interact with each other to generate sharp and asymmetric Fano profiles in transmission spectra. Finite-difference time-domain (FDTD) method and multiple interference coupled mode theory (MICMT) are employed to investigate high performances of those Fano resonances, of which sensitivity and figure of merit are high as similar to 1813 nm/RIU and similar to 57.77 dB, respectively. The proposed plasmonic MDM resonant system may promote the development of integrated photonic devices for applications in nanoscale optical sensing and optical communications.
