Objective
"Quantum Dots in Microcavities offer a unique laboratory to investigate quantum physics. The state of the art has recently achieved the so-called ""strong coupling"" where coherent quantum interactions dominate the system dynamics. Nonlinear effects of a quantum character have been shown under coherent excitation (e.g. photon blockade). An appealing framework is incoherent excitation, where the device undergoes its intrinsic dynamics in a steady state. In this case, many issues remain unresolved. One feature of full-field quantization predicted by the Jaynes-Cummings model, that describes the quantum coupling between a two-level system and a cavity, is still missing from quantum dots: the Jaynes-Cumming ladder splitting that scales like the square root of the number of photons. Such a splitting has been identified in other implementations, like atoms or superconducting qubits. In the case of semiconductors, however, puzzling features have been reported instead, like a spectral triplet. It was recently shown by the applicant that incoherent excitation brings specificities of its own in the description of light-matter interactions. This proposal aims at investigating the strong-coupling with quantum dots in microcavities in the light of this theoretical description, articulating the research in a joint theoretical/experimental collaboration between the applicant and the host organization, one of the first worldwide to achieve strong coupling in an electrically tunable photonic crystal. This opens new possibilities for exploring clean systems open to a fine external control. Beyond evidencing Jaynes-Cumming nonlinearities, this proposal will investigate spin (polarization) and Coulomb interactions (exciton complexes, biexcitons, etc.) in this nonlinear quantum context. At the climax of this work lie on-chip quantum device, such as single-photon sources or entangled-photons pair emitters, operating in the steady state of a continuous (e.g. electrical) excitation."
