Abstract
Periodic arrays of nanostructures can support collective modes known as lattice resonances that produce strong and spectrally narrow responses. Thanks to these exceptional properties, periodic arrays are being exploited in a wide variety of applications, including ultrasensitive biosensing, nanoscale light emission, and color printing, to cite a few. In this communication, we will analyze how the arrangement of the particles within the unit cell of the array determines its optical response [1-3]. We will also discuss how the interplay between the response of the individual constituents and the collective interaction dictates the ultimate limits of the field enhancement provided by these systems [4,5].
