Suppression of surface-related loss in a gated semiconductor microcavity
Daniel Najer, Natasha Tomm, Alisa Javadi +9
We present a surface passivation method that reduces surface-related losses by almost two orders of magnitude in a highly miniaturized GaAs open microcavity. The microcavity consis…
Wafer-Scale Epitaxial Modulation of Quantum Dot Density
N. Bart, C. Dangel, P. Zajac +21
Precise control of the properties of semiconductor quantum dots (QDs) is vital for creating novel devices for quantum photonics and advanced opto-electronics. Suitable low QD-densi…
Large-Range Frequency Tuning of a Narrow-Linewidth Quantum Emitter
Liang Zhai, Matthias C. Löbl, Jan-Philipp Jahn +5
A hybrid system of a semiconductor quantum dot single photon source and a rubidium quantum memory represents a promising architecture for future photonic quantum repeaters. One of…
Silicon quantum dot devices with a self-aligned second gate layer
Simon Geyer, Leon C. Camenzind, Lukas Czornomaz +5
We implement silicon quantum dot devices with two layers of gate electrodes using a self-alignment technique, which allows for ultra-small gate lengths and intrinsically perfect la…
A coherent spin-photon interface with waveguide induced cycling transitions
Martin Hayhurst Appel, Alexey Tiranov, Alisa Javadi +7
Solid-state quantum dots are promising candidates for efficient light-matter interfaces connecting internal spin degrees of freedom to the states of emitted photons. However, selec…
Near Transform-limited Quantum Dot Linewidths in a Broadband Photonic Crystal Waveguide
Freja T. Pedersen, Ying Wang, Cecilie T. Olesen +8
Planar nanophotonic structures enable broadband, near-unity coupling of emission from quantum dots embedded within, thereby realizing ideal singe-photon sources. The efficiency and…
