Photon phase shift at the few-photon level and optical switching by a quantum dot in a microcavity
L. M. Wells, S. Kalliakos, B. Villa +6
We exploit the nonlinearity arising from the spin-photon interaction in an InAs quantum dot to demonstrate phase shifts of scattered light pulses at the single-photon level. Photon…
Controllable photonic time-bin qubits from a quantum dot
J. P. Lee, L. M. Wells, B. Villa +7
Photonic time bin qubits are well suited to transmission via optical fibres and waveguide circuits. The states take the form , with $…
In-plane emission of indistinguishable photons generated by an integrated quantum emitter
Sokratis Kalliakos, Yarden Brody, Andre Schwagmann +9
We demonstrate the emission of indistinguishable photons along a semiconductor chip originating from carrier recombination in an InAs quantum dot. The emitter is integrated in the…
On-chip generation and guiding of quantum light from a site-controlled quantum dot
Ayesha Jamil, Joanna Skiba-Szymanska, Sokratis Kalliakos +9
We demonstrate the emission and routing of single photons along a semiconductor chip originating from carrier recombination in an actively positioned InAs quantum dot. Device scale…
On-chip single photon emission from an integrated semiconductor quantum dot into a photonic crystal waveguide
Andre Schwagmann, Sokratis Kalliakos, Ian Farrer +4
We demonstrate the in-plane emission of highly-polarized single photons from an InAs quantum dot embedded into a photonic crystal waveguide. The spontaneous emission rates are Purc…
Determination of Edge Purity in Bilayer Graphene Using micro-Raman Spectroscopy
Milan Begliarbekov, Onejae Sul, Sokratis Kalliakos +2
Polarization resolved micro-Raman spectroscopy was carried out at the edges of bilayer graphene. We find strong dependence of the intensity of the G band on the incident laser pola…
