Nonlinear anisotropic dielectric metasurfaces for ultrafast nanophotonics
Giuseppe Della Valle, Ben Hopkins, Lucia Ganzer +7
We report on the broadband transient optical response from anisotropic nanobrick amorphous silicon particles, exhibiting Mie-type resonances. A quantitative model is developed to i…

Active tuning of high-Q dielectric metasurfaces
Matthew Parry, Andrei Komar, Ben Hopkins +7
We demonstrate the active tuning of all-dielectric metasurfaces exhibiting high-quality factor (high-Q) resonances. The active control is provided by embedding the asymmetric silic…
