Paper Abstract

The dynamics of grating growth in both H2-loaded and non-H2-loaded GeB-doped fiber is investigated with cw 244 nm light and pulsed 266 nm light. The growth function is found to be the same in both cases, and both the growth rate and the saturation levels are proportional to the writing power density. Such a dynamics can be explained by a two- photon defect creation mechanism counterbalanced by a one- photon destruction mechanism, the saturation level being determined not by depletion of available defects, but by an equilibrium between the two mechanisms. We discuss the implications of such a model.
