Abstract

A high spectral resolution, 2D nanohole-array-based surface plasmon resonance sensor that operates at normal or near normal incidence—facilitating high spatial resolution imaging—is presented. The angular and spectral transmittance of the structure is modified from a Fano type to a pure Lorentzian line shape with a parallel and orthogonal polarizer–analyzer pair. This change leads to a linewidth narrowing that maximizes the sensor resolution, which we show to be of O ( 10 5 ) refractive index units (RIU). We estimate the potential of this system of O ( 10 6 ) RIU under optimal conditions.
