  • Title: Enhanced detection limit by dark mode perturbation in 2D photonic crystal slab refractive index sensors.
    Author: Nicolaou C, Lau WT, Gad R, Akhavan H, Schilling R, Levi O.
    Journal: Opt Express; 2013 Dec 16; 21(25):31698-712. PubMed ID: 24514742.
    Abstract:
    We demonstrate for the first time a 300nm thick, 300μm × 300μm 2D dielectric photonic crystal slab membrane with a quality factor of 10,600 by coupling light to slightly perturbed dark modes through alternating nano-hole sizes. The newly created fundamental guided resonances greatly reduce nano-fabrication accuracy requirements. Moreover, we created a new layer architecture resulting in electric field enhancement at the interface between the slab and sensing regions, and spectral sensitivity of >800 nm/RIU, that is, >0.8 of the single-mode theoretical upper limit of spectral sensitivity.
