Indistinguishable telecom band photons from a single erbium ion in the solid state
Salim Ourari, Łukasz Dusanowski, Sebastian P. Horvath +8
Atomic defects in the solid state are a key component of quantum repeater networks for long-distance quantum communication. Recently, there has been significant interest in rare ea…
On-chip Hong-Ou-Mandel interference from separate quantum dot emitters in an integrated circuit
Łukasz Dusanowski, Dominik Köck, Christian Schneider +1
Scalable quantum photonic technologies require low-loss integration of many identical single-photon sources with photonic circuitry on a chip. Relatively complex quantum photonic c…
Observation of room temperature excitons in an atomically thin topological insulator
Marcin Syperek, Raul Stühler, Armando Consiglio +10
Optical spectroscopy of ultimately thin materials has significantly enhanced our understanding of collective excitations in low-dimensional semiconductors. This is particularly ref…
Using the Autler-Townes and ac Stark effects to optically tune the frequency of indistinguishable single-photons from an on-demand source
Chris Gustin, Łukasz Dusanowski, Sven Höfling +1
We describe how a coherent optical drive that is near-resonant with the upper rungs of a three-level ladder system, in conjunction with a short pulse excitation, can be used to pro…
Optical Charge Injection and Full Coherent Control of Spin-Qubit in the Telecom C-band Emitting Quantum Dot
Łukasz Dusanowski, Cornelius Nawrath, Simone L. Portalupi +5
Solid-state quantum emitters with manipulable spin-qubits are promising platforms for quantum communication applications. Although such light-matter interfaces could be realized in…
Relaxation Oscillations and Ultrafast Emission Pulses in a Disordered Expanding Polariton Condensate
Maciej Pieczarka, Marcin Syperek, Łukasz Dusanowski +5
Semiconductor microcavities are often influenced by structural imperfections, which can disturb the flow and dynamics of exciton-polariton condensates. Additionally, in exciton-pol…
Ghost Branch Photoluminescence From a Polariton Fluid Under Nonresonant Excitation
Maciej Pieczarka, Marcin Syperek, Łukasz Dusanowski +8
An expanding polariton condensate is investigated under pulsed nonresonant excitation with a small laser pump spot. Far above the condensation threshold we observe a pronounced inc…
