The research team was composed of University of North Carolina at Charlotte, Clemson University, University of Texas at Arlington, andUniversity of Minnesota. The scope of this program was to change the way components are designed and fabricated for high energy laser HEL applications, engineering electromagnetic fields in 3D dielectric structures. We exploited various methods based on periodic and aperiodic electromagnetic modeling techniques to accurately determine the fields throughout the structures. We developed methods of optimizing the desired spatial, spectral and polarization properties for specific platforms representational of High Energy Laser Components. Fabrication of structures with this degree of complexity requires unique methods of lithographic processing, etching and deposition. Advanced deposition methods were explored to provide high quality coatings based on atomic layer deposition and enable the engineering of structures on a monolayer by monolayer basis, with particular attention to laser-damage mechanisms. Test-beds were used to demonstrate the concept functionality, including solid-state-laser and fiber-laser based HEL systems. From and educational perspective we created a virtual laboratory for 3D Meta-Optics.
