Phase analysis of superradiance of a quantum-dot ensemble

The phase analysis of the dynamic equations obtained on the basis of both a microscopic representation of the polarization of a quantum-dot ensemble and the difference of electron-level populations is carried out. It is shown that, under pumping and real relations between the parameters of a quantum-dot ensemble, the superradiance is realized in the form of a giant pulse regardless of the resonator frequency detuning and the coupling parameters. The obtained results are compared with experimental data.
