Abstract

Recently, we have proposed a novel approach for fabrication of asymmetric metal-dielectric (hybrid) nanoparticles via combination of standard lithography processes and femtosecond laser reshaping of a metal component of the nanoparticle. Here, we study the influence of the geometrical parameters of the hybrid nanoparticle on the reshaping process. We also demonstrate non-reversible tuning of light absorbtion and reversible tuning of transmittance of the hybrid nanostructures in a wide range.
