Stop of light in nonlinear photonic crystal

A new effect of light localization in nonlinear layers of photonic crystal is predicted. It is shown that during the initial pulse propagation through the nonlinear medium an ultra-short high-intensity solitons, which are reflected from the boundaries of the linear and nonlinear layers as a whole, are formed. Hence, the soliton sub-pulses are captured by the nonlinear layer of the photonic crystal. Soliton interaction is discussed as well. Computer simulation based on a new approach for this class of problems is proposed by the authors.
