Abstract
Conventional hydrogen loading of phosphosilicate optical fibers at relatively low temperatures (80 °C) is sufficient to enhance the fiber’s photosensitivity after hydrogen outdiffusion, allowing permanent Bragg grating structures to be produced. Thermal sensitization is proposed to be a major contributor to stable index change.
