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.
