Aberrations in (3+1)D Bragg diffraction using pulsed Gaussian laser beams
Antje Neumann, Martina Gebbe, Reinhold Walser
We analyze the transfer function of a three-dimensional atomic Bragg beamsplitter formed by two counterpropagating pulsed Gaussian laser beams. Even for ultracold atomic ensembles,…
Raman velocity filter as a tool for collinear laser spectroscopy
Antje Neumann, Wilfried Nörtershäuser, Reinhold Walser
The velocity distribution of a hot ionic beam can be filtered with a narrow stimulated Raman process to prepare a colder subensemble, as substantiated in this theoretical analysis.…
Stopped and stationary light at the single-photon level inside a hollow-core fiber
Thorsten Peters, Ta-Pang Wang, Antje Neumann +2
An experimental platform operating at the level of individual quanta and providing strong light-matter coupling is a key requirement for quantum information processing. We report o…
Non-resonant feeding of photonic crystal nanocavity modes by quantum dots
A. Laucht, N. Hauke, A. Neumann +9
We experimentally probe the non-resonant feeding of photons into the optical mode of a two dimensional photonic crystal nanocavity from the discrete emission from a quantum dot. Fo…
Phonon-assisted transitions from quantum dot excitons to cavity photons
Ulrich Hohenester, Arne Laucht, Michael Kaniber +4
For a single semiconductor quantum dot embedded in a microcavity, we theoretically and experimentally investigate phonon-assisted transitions between excitons and the cavity mode.…
Cavity-resonant excitation for efficient single photon generation
M. Kaniber, A. Neumann, A. Laucht +3
We present an efficiently pumped single photon source based on single quantum dots (QD) embedded in photonic crystal nanocavities. Resonant excitation of a QD via a higher order ca…
