ABSTRACT
In this chapter, we review our work on the engineering of aperiodic
order for nanoplasmonics device applications. In particular, we
discuss the optical response of aperiodic arrays of metallic nanopar-
ticles, referred to as deterministic aperiodic nanostructures (DANS).
These plasmonic media, conceived by designing spatial frequencies
in aperiodic Fourier space, give rise to characteristic scattering
resonances and localized mode patterns that enhance the intensity
of optical near fields over planar surfaces and broad frequency
spectra. Moreover, the distinctive interplay between photonic
diffraction and near-field plasmonic localization in DANS provides
novel opportunities to manipulate light-matter interactions on the
nanoscale for the engineering of device applications in optical
biosensing, plasmon-enhanced light sources, solar cells, nonlinear
frequency generation, and singular optics.
