Cryptography metasurface for one-time-pad
WebDec 16, 2024 · The metasurface was designed by using the Pancharatnam-Berry phase ( 40, 41) and was fabricated by scanning a femtosecond pulse laser inside a silica slab (around 50 μm beneath the surface). The self-assembled nanostructures inside of the silica slab are formed under intense laser irradiation.
