Coherent dynamics of one and two-photon states in a strongly coupled single quantum dot-cavity system

Heterodyne spectral interferometry is employed to perform four-wave mixing spectroscopy on a strongly-coupled system of an exciton confined in a single quantum dot and a photon mode of a pillar microcavtity. The coherent dynamics of one and two photon states are directly observed and the validity of the Janes-Cummings model is tested.

Ultrafast Photon-Photon Interaction in a Strongly Coupled Quantum Dot-Cavity System

Dirk Englund, Arka Majumdar, Michal Bajcsy +3 more

We study dynamics of the interaction between two weak light beams mediated by a strongly coupled quantum dot-photonic crystal cavity system. First, we perform all-optical switching of a weak continuous-wave signal with a pulsed control beam, and then perform switching between two weak pulsed beams (40 ps pulses). Our results show that the quantum dot-nanocavity system enables fast, controllable optical switching at the single-photon level.

Single-photon absorption and dynamic control of the exciton energy in a coupled quantum-dot–cavity system

R. Johne, Andrea Fiore

We theoretically investigate the dynamic interaction of a quantum dot in a nanocavity with time-symmetric single-photon pulses. The simulations, based on a wave-function approach, reveal that almost perfect single-photon absorption occurs for quantum-dot--cavity systems operating on the edge between strong- and weak-coupling regimes. The computed maximum absorption probability is close to unity for pulses with a typical length comparable to half of the Rabi period. Furthermore, the dynamic control of the quantum-dot energy via electric fields allows the freezing of the light-matter interaction, leaving the quantum dot in its excited state. Shaping of single-photon wave packets by the electric field control is limited by the occurrence of chirping of the single-photon pulse. This understanding of the interaction of single-photon pulses with the quantum-dot--cavity system provides the basis for the development of advanced protocols for quantum-information processing in the solid state.
