Coherent superposition of emitted and resonantly scattered photons from a two-level system in a cavity driven by an even-$\pi$ pulse

Abstract:We examine the nature and quantum satistics of a multiphoton bunch generated under resonant excitation by even-$\pi$ pulses of a charged quantum dot in a cavity. Experiments with Rabi oscillations in time-resolved photoluminescence, varying pulse duration, and cavity mode detuning show that this multiphoton state is a coherent superposition of emitted photons and resonantly scattered laser photons. The developed model incorporates both resonant scattering and re-excitation mechanisms, allowing us to describe the quantum statistics of the multiphoton state, which is controlled by the coupling between the quantum dot and optical modes in the cavity.
