Deterministic integration of quantum dots into on-chip multi-mode interference beamsplitters using in-situ electron beam lithography
Peter Schnauber, Johannes Schall, Samir Bounouar +8
The development of multi-node quantum optical circuits has attracted great attention in recent years. In particular, interfacing quantum-light sources, gates and detectors on a sin…
GaAs droplet quantum dots with nanometer-thin capping layer for plasmonic applications
Suk In Park, Oliver Joe Trojak, Eunhye Lee +6
We report on the growth and optical characterisation of droplet GaAs quantum dots with extremely-thin (11 nm) capping layers. To achieve such result, an internal thermal heating st…
Zero bias conductance peak in InAs nanowire coupled to superconducting electrodes
Nam-Hee Kim, Yun-Sok Shin, Hong-Seok Kim +2
We report the occurrence of the zero-bias conductance peak (ZBCP) in an InAs nanowire coupled to PbIn superconductors with varying temperature, bias voltage, and magnetic field. Th…
Direct Transfer of Light's Orbital Angular Momentum onto Non-resonantly Excited Polariton Superfluid
Byoung Yong Oh, Min-Sik Kwon, Su-Hyun Gong +6
Recently, exciton-polaritons in a semiconductor microcavity were found to condense into a coherent ground state much like a Bose-Einstein condensate and a superfluid. They have bec…
Indistinguishable and efficient single photons from a quantum dot in a planar nanobeam waveguide
Gabija Kiršanskė, Henri Thyrrestrup, Raphaël S. Daveau +16
We demonstrate a high-purity source of indistinguishable single photons using a quantum dot embedded in a nanophotonic waveguide. The source features a near-unity internal coupling…
