A gated quantum dot far in the strong-coupling regime of cavity-QED at optical frequencies
Daniel Najer, Immo Söllner, Pavel Sekatski +10
The strong-coupling regime of cavity-quantum-electrodynamics (cQED) represents light-matter interaction at the fully quantum level. Adding a single photon shifts the resonance freq…
Deterministic enhancement of coherent photon generation from a nitrogen-vacancy center in ultrapure diamond
Daniel Riedel, Immo Söllner, Brendan J. Shields +5
The nitrogen-vacancy (NV) center in diamond has an optically addressable, highly coherent spin. However, an NV center even in high quality single-crystalline material is a very poo…
Fabrication of mirror templates in silica with micron-sized radii of curvature
Daniel Najer, Martina Renggli, Daniel Riedel +2
We present the fabrication of exceptionally small-radius concave microoptics on fused silica substrates using CO2 laser ablation and subsequent reactive ion etching. The protocol y…
Towards high cooperativity strong coupling of a quantum dot in a tunable microcavity
Lukas Greuter, Sebastian Starosielec, Andreas V. Kuhlmann +1
We investigate the strong coupling regime of a self-assembled quantum dot in a tunable microcavity with dark-field laser spectroscopy. The high quality of the spectra allows the li…
