Systematic Tuning Mechanisms with Aperiodic and Disordered Plasmonic Nanostructures

Project Description:
This work focuses on systematically adjusting properties of aperiodic, disordered, or random lattices to tune the spectral responses of 2D plasmonic arrays. We investigate a broad variety of structures that we group into ordered, uncorrelated, repulsive, and attractive classes. We demonstrate that uncorrelated structures can result in smoother optical spectra as a structure becomes more disordered. However, this smoothness is limited, and can be further tuned by an order of magnitude via attractive point processes.
