  • OPTICAL GAIN MATERIALS FOR HIGH ENERGY LASERS AND LASER ILLUMINATORS AND METHODS OF MAKING AND USING SAME
    Publication number: 20230223741
    Abstract: Core-cladding planar waveguide (PWG) structures and methods of making and using same. The core-cladding PWG structures can be synthesized by hydride vapor phase epitaxy and processed by mechanical and chemical-mechanical polishing. An Er doping concentration of [Er] between 1×1018 atoms/cm3 and 1×1022 atoms/cm3 can be in the core layer. Such PWGs have a core region that can achieve optical confinement between 96% and 99% and above.
