ABSTRACT: Photon storage with nanosecond switching was implemented with indirect excitons in coupled quantum well nanostructures. The storage and release of photons was controlled by the gate voltage pulses. The nanosecond write and readout times were much shorter than the storage time, which reached microseconds. Furthermore, the presented control of excitons on a time scale much shorter than the exciton lifetime demonstrates the feasibility of studying excitons in in situ controlled electrostatic traps.
