Demonstration of large aperture tailorable meta-surfaces with superior mechanical and laser power durability

We present an alternative approach to dielectric meta-surfaces and demonstrate its scalability, mechanical durability and laser damage resilience. The process is based on laser raster-scan of a thin metal film on a glass, followed by dry-etching and removal of the metal nano-particles mask. We will present new approaches developed to “boost” the attainable optical response based on new underlying physics of the laser printed Au nanoparticle mask.
