    Abstract
    We report a novel ultra-short pulse emitter utilizing transient charge carrier behavior and cooperative emission in multiple wide-quantum-well heterostructures. Its optical cavity reassembles a tandem-cavity laser diode with electroabsorber section surrounded by two gain sections. With selection of the electrical pump pulse and the absorber voltage, due to quantum-confined Stark effect in wide quantum well, it is possible to spatially pull the electrons and holes apart from each other. When the pump bias is removed, an ultra-short pulse due to cooperative recombination of electrons and holes emerges. We demonstrate that such cooperative superradiance produces non-classical high-order correlations in the emitted light while Wigner function of the state reveals quantum oscillations.
