Coherent versus incoherent modulation of a resonant level: the effect of modulation noise on the propagation of light through quantum wells.
The propagation of a weak light beam through a quantum well in the vicinity of an excitonic resonance that is modulated harmonically in time at terahertz frequency is considered. It is found that the reflection probability of the light beam is considerably different in the cases of purely coherent versus Gaussian incoherent terahertz modulation, even in the limit of long coherence times.
