Abstract :
The dynamics of Bragg grating growth in UV-sensitized, hydrogen saturated silica fibers are explained using a transient kinetic model. Re-circulation of hydrogen, functioning as catalyst in the photosensitive reactions is believed to be responsible for the increase in the steady state value of the refractive index changes.
