Paper Abstract

The ability to design and to control light matter interactions on the nanoscale represents the core aspect of the rapidly growing fields of nanophotonics and nanoplasmonics. Efficient schemes for electromagnetic field localization and enhancement over broad frequency spectra are essential requirements for the engineering of novel optoelectronic technologies that leverage on enhanced optical cross sections. In particular, the study of deterministic arrays of resonant nanostructures without translational invariance offers an enormous potential for the manipulation of localized optical states and broad frequency spectra. Deterministic Aperiodic Nano Structures (DANS), are generated by mathematical rules with spectral features that interpolate in a tunable fashion between periodic crystals and disordered random media. In this paper, we will focus on the optical properties and device applications of planar DANS in relation to plasmon-enhanced light emission, Surface Enhanced Raman Scattering, and optical biosensing.
