Abstract

We present a scalable method for producing all-glass meta-surfaces with high mechanical stability and robust resistance to laser-induced damage. The process is based on dewetting a thin metal film on a glass substrate, followed by dry etching and metal mask removal. Laser scan is used to pattern the spatial pattern of the end-result metasurface. We will present process advances which enable formation of lenses, antireflection surfaces, and birefringence elements.
