All-optical tuning of a photonic band-gap via near-infrared laser pulses

Risultato della ricerca: Other

Abstract

We present an all-optical tuning at IR wavelength in a novel photonic crystal consisting of a polystyrene opal with gold nanoparticles. The band-gap can be finely tuned with permanent shifts as large as 30 nm irradiating the sample with ps pulses at a low rep-rate in the visible.
