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…
Epitaxial lift-off for solid-state cavity quantum electrodynamics
Lukas Greuter, Daniel Najer, Andreas V. Kuhlmann +5
We present a new approach to incorporate self-assembled quantum dots into a Fabry-Pérot-like microcavity. Thereby a 3/4 GaAs layer containing quantum dots is epitaxially removed…
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…
A small mode volume tunable microcavity: development and characterization
Lukas Greuter, Sebastian Starosielec, Daniel Najer +4
We report the realization of a spatial and spectrally tunable air-gap Fabry-Perot type microcavity of high finesse and cubic-wavelength-scale mode volume. These properties are attr…
