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…
Spatially shaping waves to penetrate deep inside a forbidden gap
Ravitej Uppu, Manashee Adhikary, Cornelis A. M. Harteveld +1
It is well known that waves incident upon a crystal are transported only over a limited distance - the Bragg length - before being reflected by Bragg interference. Here, we demonst…
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…
Scalable integrated single-photon source
Ravitej Uppu, Freja T. Pedersen, Ying Wang +8
Photonic qubits are key enablers for quantum-information processing deployable across a distributed quantum network. An on-demand and truly scalable source of indistinguishable sin…
Deterministic and controllable photonic scattering media via direct laser writing
E. Marakis, R. Uppu, M. L. Meretska +3
Photonic scattering materials, such as biological tissue and white paper, are made of randomly positioned nanoscale inhomogeneities in refractive index that lead to multiple scatte…
On-chip deterministic operation of quantum dots in dual-mode waveguides for a plug-and-play single-photon source
Ravitej Uppu, Hans T. Eriksen, Henri Thyrrestrup +9
A deterministic source of coherent single photons is an enabling device of quantum-information processing for quantum simulators, and ultimately a full-fledged quantum internet. Qu…
