Aperiodic Order in Nanoplasmonics

摘要: In this chapter, we review our work on the engineering of aperiodic order for nanoplasmonics device applications. particular, discuss optical response arrays metallic nanoparticles with Fourier spectral features that interpolate in a tunable fashion between periodic crystals and disordered random media, referred to as Deterministic Aperiodic Nano Structures (DANS). These plasmonic structures, conceived by designing spatial frequencies space, give rise characteristic scattering resonances localized mode patterns enhancing intensity near fields over planar surfaces broad frequency spectra. Moreover, distinctive interplay photonic diffraction field localization DANS provides novel opportunities manipulate light-matter interactions nanoscale applications biosensing, plasmon-enhanced light sources, solar cells, nonlinear generation, singular optics.
