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 1×10atoms/cmand 1×10atoms/cmcan be in the core layer. Such PWGs have a core region that can achieve optical confinement between 96% and 99% and above.
