What is it about?

We discuss simulations of electromagnetic fields interacting with arrays silicon nanoparticles. The design of the nanoparticles and of the arrays allows enhancing the fields by the so-called lattice resonances.

Why is it important?

This is the first detailed investigation of surface lattice resonances using silicon nanoparticles instead of the more thoroughly investigated arrays of metallic nanoparticles.

Perspectives

Lattice resonances have been mostly investigated with metallic nanoparticles, where losses are inherent. The use of silicon nanoparticles allows the reduction of these losses, which opens new opportunities in applications such as sensing, photovoltaics or light emission of fluorophores in the proximity of the array.
