Abstract
The demonstration of ultrafast suppression and recovery of an active photonic band-gap structure constructed from the periodic complex susceptibility of quantum well excitons was presented. The superradiant mode was slaved by the external field for resonant pumping and the structure formed a mirror which could be switched on and off at a bandwidth. The bandwidth was limited only by the width of the pump-pulse and the photonic band gap.
