Modulation of plasmonic Fano resonance by the shape of the nanoparticles in ordered arrays
Abstract
The modulation of Fano resonance by nanoparticle shape in ordered arrays is studied. The variation of the particle plasmon resonance mode changes the interference with the photonic modes of the particle in array that consequently shifts the Fano resonance mode. The elongation of the nanodiscs in arrays allowed modulation of Fano resonance via the changing of electromagnetic field propagation by particles' orientation and light polarization.
