    Journal: Philos Trans A Math Phys Eng Sci; 2017 Mar 28; 375(2090):. PubMed ID: 28220001.
    Abstract:
    We demonstrate experimentally refractive index sensing with localized Fano resonances in silicon oligomers, consisting of six disks surrounding a central one of slightly different diameter. Owing to the low absorption and narrow Fano-resonant spectral features appearing as a result of the interference of the modes of the outer and the central disks, we demonstrate refractive index sensitivity of more than 150 nm RIU-1 with a figure of merit of 3.8.This article is part of the themed issue 'New horizons for nanophotonics'.
