  • Observation of Mollow Triplets with Tunable Interactions in Double Lambda Systems of Individual Hole Spins PHYSICAL REVIEW LETTERS Lagoudakis, K. G., Fischer, K. A., Sarmiento, T., McMahon, P. L., Radulaski, M., Zhang, J. L., Kelaita, Y., Dory, C., Muller, K., Vuckovic, J. 2017; 118 (1)

    Abstract

    Although individual spins in quantum dots have been studied extensively as qubits, their investigation under strong resonant driving in the scope of accessing Mollow physics is still an open question. Here, we have grown high quality positively charged quantum dots embedded in a planar microcavity that enable enhanced light-matter interactions. Under a strong magnetic field in the Voigt configuration, individual positively charged quantum dots provide a double lambda level structure. Using a combination of above-band and resonant excitation, we observe the formation of Mollow triplets on all optical transitions. We find that when the strong resonant drive power is used to tune the Mollow-triplet lines through each other, we observe anticrossings. We also demonstrate that the interaction that gives rise to the anticrossings can be controlled in strength by tuning the polarization of the resonant laser drive. Quantum-optical modeling of our system fully captures the experimentally observed spectra and provides insight on the complicated level structure that results from the strong driving of the double lambda system.

  • Complete Coherent Control of a Quantum Dot Strongly Coupled to a Nanocavity SCIENTIFIC REPORTS Dory, C., Fischer, K. A., Mueller, K., Lagoudakis, K. G., Sarmiento, T., Rundquist, A., Zhang, J. L., Kelaita, Y., Vuckovic, J. 2016; 6

    Abstract

    Strongly coupled quantum dot-cavity systems provide a non-linear configuration of hybridized light-matter states with promising quantum-optical applications. Here, we investigate the coherent interaction between strong laser pulses and quantum dot-cavity polaritons. Resonant excitation of polaritonic states and their interaction with phonons allow us to observe coherent Rabi oscillations and Ramsey fringes. Furthermore, we demonstrate complete coherent control of a quantum dot-photonic crystal cavity based quantum-bit. By controlling the excitation power and phase in a two-pulse excitation scheme we achieve access to the full Bloch sphere. Quantum-optical simulations are in good agreement with our experiments and provide insight into the decoherence mechanisms.
