Polarized light bursts from kicked quantum rings
arXiv:0805.2364 · doi:10.1103/PhysRevA.78.051804
Abstract
Non-equilibrium quantum rings emit circular polarized subterahertz radiation with a polarization degree controllable on nano- to picosecond time scales. This we conclude using a theory developed here for the time-dependent detection of the circular polarization of polychromatic radiations, valid for time scales comparable to the reciprocal of characteristic emission frequencies. The theory is applied to driven quantum rings whereby the influence of radiative and non-radiative processes on the properties of the emitted light is incorporated.
