Possibility of coherent light emission from Bose condensed states of SEHPs

The possibility of Bose condensation of excitons has been predicted in a system with spatially separated electron hole pairing (SEHP), e.g. a GaAs/AlGaAs double quantum well separated by a thin quantum barrier. Coherent recombination emission has been expected, due to the transfer of coherence from the condensed excitons to the photon field. © 1990.
