Superabsorption of light by nanoparticles

Ladutenko, Konstantin; Belov, Pavel; Peña-Rodríguez, Ovidio; Mirzaei, Ali; Miroshnichenko, Andrey; Shadrivov, Ilya

Description

Nanoparticles have a fundamental limit as to how much light they can absorb. This limit is based on the finite number of modes excited in the nanoparticle at a given wavelength and maximum absorption capacity per mode. The enhanced absorption can be achieved when each mode supported by the nanoparticle absorbs light up to the maximum capacity. Using a stochastic optimization algorithm, we design multilayer nanoparticles, in which we can make several resonant modes overlap at the same frequency...[Show more]
