Abstract
We investigate optical pulse localization at its propagation in 2D layered photonic crystal (PC) with cubic nonlinear response. In the case under consideration, a light localization takes place due to spatial solitons appearing in certain PC elements. Soliton velocity depends on its intensity and location in the PC. This results in sub-pulses velocities changing which reflect from the PC or transmit through the PC. The formation of soliton depends on input light intensity, duration of pulse and length of the elements from which the PC consists. The soliton may move with slow velocity inside the PC elements. Under certain conditions, the soliton can stop near the PC boundaries. This phenomenon can be used for data storage.
