Paper Abstract

Fano resonance is investigated by finite element method in plasmonic waveguide system which comprise a stub and a side coupled split ring resonator. We show that Fano resonance wavelength has a linear relation with refractive index of the material. Based on the sensitivity to the circumstance, a high performance refractive index sensor is proposed. This sensor can take advantage of easy on-chip integration of SPPs and high sensitivity of Fano resonance. This work may provide guidance for the design of on-chip nanosensors and other applications in integrated optical circuit.
