In this work, we show the feasibility of all-optical control of time delay in a Bragg grating with an active defect that consists in an asymmetric double quantum-well GaAs/Al x Ga 1Àx As. The double quantum-well is modeled as a K-V-type four level system. The refractive index of the defect can be mo
