The propagation of probe electromagnetic waves has been investigated in a heterostructure formed by layers having linear and nonlinear optical properties. The appearance of a forbidden bandgap for the probe electromagnetic field induced by another control electromagnetic field has been shown that leads to the trapping of the probe pulse inside the structure. Switching off the control field leads to resuming the propagation of the probe pulse. Implementation of nonlinear layer has been suggested. (C) 2015 Optical Society of America
