Abstract
Conventional hydrogen loading of phosphosilicate optical fibers at relative ly low temperatures (80 degreesC) is sufficient to enhance the fiber's phot osensitivity after hydrogen outdiffusion, allowing permanent Bragg grating structures to be produced. Thermal sensitization is proposed to be a major contributor to stable index change. (C) 2001 Optical Society of America.
