New paper about nonlinear photonics with Barium Titanate metasurfaces
As part of our research on nonlinear photonics for a broad optical range, we show that periodic arrays of BaTiO3 nanodisks, also called metasurfaces, reshape the amplitude of linear and SHG light over the subwavelength scale down to the near-ultraviolet range.

The fabrication of these BaTiO3 metasurfaces was made possible by our ongoing collaboration with the group of Manfred Fiebig, where BaTiO3 layers were grown on a transparent and amorphous glass substrate.
