Abstract

In this work, we propose an all-optical controllable double state switch using the dipole induced transparency effect applied on multilevel nanocrystal doped to photonic crystal (PC) cavity. Using the proposed structure, with applying one control field the absorbing medium converted to transparent one and switching operation is obtained and then applying the second control field changes the transparent PC cavity to opaque one again. Analytical relation for the proposed switch is presented and studied by investigation of effects of parameters on switching characteristics.
