Abstract
Fiber Bragg gratings were fabricated by utilizing high pressure deuterium loading for photosensitivity enhancement and a phase mask for holographic exposure. The absorption peak near 1.71 micrometers was used as an indicator to monitor the evolution of deuterium diffusion into and out of a fiber, and the results were consistent with the theoretical modeling. Thermal hysteresis of the fiber Bragg grating was greatly reduced and thermal reliability was increased when annealing was applied.
