Modulating light with light via giant nano-opto-mechanical nonlinearity of plasmonic metamaterial
Jun-Yu Ou, Eric Plum, Jianfa Zhang +1
From the demonstration of saturable absorption by Vavilow and Levshin in 1926, and with invention of the laser, unavailability of strongly nonlinear materials was a key obstacle fo…
Tunable asymmetric transmission of THz wave through a graphene planar chiral structure
Junyang Zhao, Jianfa Zhang, Zhihong Zhu +2
In this letter, we show that asymmetric transmission of circularly polarized waves through a nanostructured planar chiral graphene film can be observed in terahertz range. The asym…
Invisible nanowires with interfering electric and toroidal dipoles
Wei Liu, Jianfa Zhang, Bing Lei +2
By studying the scattering of normally incident planewaves by a single nanowire, we reveal the indispensable role of toroidal multipole excitation in multipole expansions of radiat…
Toroidal dipole induced transparency for core-shell nanoparticles
Wei Liu, Jianfa Zhang, Andrey E. Miroshnichenko
We investigate the scattering properties of spherical nanoparticles by employing a Cartesian multipole expansion method which has incorporated radiating toroidal multipoles. It is…
