Subwavelength gratings for OVDs - From local interactions to using light-transport
Guillaume Basset, Giorgio Quaranta, Fabian Lütolf +2
In the past 30 years, subwavelength gratings have been developed and produced as highly secured Diffractive Optical Variable Image Devices (DOVIDs). They allowed new distinct optic…
