Abstract

An opportunity of realization of optical memory and optical switching under the two-wave action on 1D photonic crystal (layered structure) with cubic nonlinearity is demonstrated on the base of computer simulation. Proposed scheme of interaction concludes in an action of laser pulse with different wavelengths. First, after action of one of them an optical soliton appears in some layers and part of optical energy localizes in nonlinear photonic crystal. Then, a pulse with different wavelength acts on the photonic crystal. As a consequence of it, the light energy of laser pulse with the previous wavelength leaves the photonic crystal while the laser energy of acting pulse localizes in the crystal due to formation of new soliton in this layer. This process can be repeated many times. The replacement of radiation with one wavelength on radiation with other wavelength takes place under the action of sequence of laser pulse with definite wavelength. A duration and maximum intensity of pulse from this sequence determine a speed of light energy exchange and an efficiency of radiation replacement.
