Paper Abstract

An effect of light localization in nonlinear 1-D photonic crystal (PC) with a few layers pairs is considered. Computer simulation of the femtosecond pulse propagation shown a self-formation of ultra-short high-intensity solitons, which reflect from boundaries of linear and nonlinear layers as whole if nonlinear PC layers alternate with the linear ones. The variation (up to 20%) of PC layer's length doesn't change the localization process essentially. It results in increasing of input pulse intensity for which localization takes place. This aspect is very important for observing of effect in physical experiment. The stronger variation can either increase the quantity of initial pulse energy localized in PC, either damp the localization at all under the condition of unvaried intensity of input pulse. Computer simulation based on a new approach for this class of problems proposed by authors recently. Our method has advantages in comparison to the widely used splitting method.
