We formulate a Monte Carlo approach suitable for an analysis of the kinetics of a hypothetical process of temperature-controlled writing of diffraction gratings in doped azo-polymers. This method uses a recently proposed kinetic model of temperaturedependent evolution of gratings during writing/erasure. It is shown that a sudden change of the temperature leads to a substantial increase of the speed of information storage. Closely related experimental results obtained using degenerate two-wave mixing (DTWM) method are presented.
