Radiative Auger Process in the Single-Photon Limit
Matthias C. Löbl, Clemens Spinnler, Alisa Javadi +8
In a multi-electron atom, an excited electron can decay by emitting a photon. Typically, the leftover electrons are in their ground state. In a radiative Auger process, the leftove…
On-chip nanomechanical filtering of quantum-dot single-photon sources
Xiaoyan Zhou, Ravitej Uppu, Zhe Liu +6
Semiconductor quantum dots in photonic integrated circuits enable scaling quantum-information processing to many single photons and quantum-optical gates. On-chip spectral filters…
Suspended Spot-Size Converters for Scalable Single-Photon Devices
Aslı D. Uğurlu, Henri Thyrrestrup, Ravitej Uppu +6
We report on the realization of a highly efficient optical spot-size converter for the end-face coupling of single photons from GaAs-based nanophotonic waveguides with embedded qua…
