Abstract: The possibility to use phasic effect to turn off a coherent population trapping for creating a switcher of the light propagation direction in an electromagnetically induced gratings in the medium with $\Lambda$-atoms is studied theoretically in this paper. The allowable scope of the effect is determined. The parameters that allowed to obtain a highly efficient scheme of spatial redistribution of the intensity of the probe field on atomic density gratings were obtained and studied.

Keywords: electromagnetically induced gratings, all-optical devices, optical switch, optical router.
