Abstract
The invention includes environmentally stable athermalized optical fiber gratings and methods of making such stabilized optical waveguide fiber grating. Stable humidity-resistant athermalized fiber Bragg gratings are provided by stabilizing a negative thermal expansion substrate and utilizing a durable frit to attach the fiber Bragg grating to the substrate.
