Monipulation of Light Propagation in Photonic Crystal

A propagation of probe electromagnetic waves have been investigated in a heterostructure formed by linear and nonlinear layers. The appearance of a forbidden band gap for a probe electromagnetic field induced by another control electromagnetic field has been shown to lead to trapping of a probe pulse inside structure. Switching off the control field leads to resuming the propagation of the probe pulse. Implimentation of nonlinear layer has been suggested.
