Since todays Internet traffic is more and more concentrated in hyperscale datacenters,1 new concepts for shortrange optical communication systems with high modulation bandwidth, high temperature stability, and low energy consumption are urgently need

We report photoluminescence emission from single self-assembled InAlGaAs quantum dots, which is broadened purely by dephasing processes. We observe linewidths as low as View the MathML source at View the MathML source, which agrees with the homogeneo

We report measurements of ultra-long coherence in self-assembled quantum dots. Transient four-wave mixing experiments at 5 K show an average dephasing time of 372 ps, corresponding to a homogeneous linewidth of 3.5 μ eV, which is significantly small

We report the first investigation of resonant secondary emission from quantum well excitons using ultrafast spectral interferometry. Observation of high-contrast spectral fringes demonstrates a significant phase correlation of the spectral components

A systematic study of the photoluminescence from double quantum well in p-i-n GaAs/AlGaAs/GaAs heterostructure under the influence of an external electric and magnetic field at different temperatures has been performed. The luminescence peak of the i
