Sol-gel Barium Titanate Nanohole Array as a Nonlinear Metasurface and a Photonic Crystal
Ülle-Linda Talts, Helena C. Weigand, Grégoire Saerens +6
The quest of a nonlinear optical material that can be easily nanostructured over a large surface area is still ongoing. Here, we demonstrate a nanoimprinted nonlinear barium titana…
