Impact of temporal correlations, coherence, and postselection on two-photon interference
Fernando Redivo Cardoso, Jaewon Lee, Riccardo Checchinato +6
Two-photon interference is an indispensable resource in quantum photonics, but it is not straightforward to achieve. The cascaded generation of photon pairs contains intrinsic temp…
Post-fabrication tuning of circular Bragg resonators for enhanced emitter-cavity coupling
Tobias M. Krieger, Christian Weidinger, Thomas Oberleitner +12
Solid-state quantum emitters embedded in circular Bragg resonators are attractive due to their ability to emit quantum states of light with high brightness and low multi-photon pro…
Time-bin entanglement at telecom wavelengths from a hybrid photonic integrated circuit
Hannah Thiel, Lennart Jehle, Robert J. Chapman +9
Mass-deployable implementations for quantum communication require compact, reliable, and low-cost hardware solutions for photon generation, control and analysis. We present a fiber…
Mid-Infrared Ring Interband Cascade Laser: Operation at the Standard Quantum Limit
Georg Marschick, Jacopo Pelini, Tecla Gabbrielli +9
Many precision applications in the mid-infrared spectral range have strong constraints based on quantum effects that are expressed in particular noise characteristics. They limit,…
Polariton-dark exciton interactions in bistable semiconductor microcavities
Elena Rozas, Evgeny Sedov, Yannik Brune +3
We take advantage of the polariton bistability in semiconductor microcavities to estimate the interaction strength between lower exciton-polariton and dark exciton states. We combi…
Strain-free GaSb quantum dots as single-photon sources in the telecom S-band
Johannes Michl, Giora Peniakov, Andreas Pfenning +7
Creating single photons in the telecommunication wavelength range from semiconductor quantum dots (QDs) and interfacing them with spins of electrons or holes has been of high inter…
Impact of MBE-grown (In,Ga)As/GaAs metamorphic buffers on excitonic and optical properties of single quantum dots with single-photon emission tuned to the telecom range
Paweł Wyborski, Michał Gawełczyk, Paweł Podemski +6
Tuning GaAs-based quantum emitters to telecom wavelengths makes it possible to use the existing mature technology for applications in, e.g., long-haul ultra-secure communication in…
Beyond equivalent circuit representations in nonlinear systems with inherent memory
V. Lopez-Richard, S. Pradhan, R. S. Wengenroth Silva +4
Basic multimode impedance analysis grounded in the availability of nonequilibrium charge carriers and their retarded path towards equilibrium is used to access the inadequacy of eq…
Confined-state physics and signs of fermionization of moiré excitons in WSe/MoSe heterobilayers
Frederik Lohof, Johannes Michl, Alexander Steinhoff +10
We revisit and extend the standard bosonic interpretation of interlayer excitons in the moiré potential of twisted heterostructures of transition-metal dichalcogenides. In our expe…
Lasing of Moiré Trapped MoSe/WSe Interlayer Excitons Coupled to a Nanocavity
Chenjiang Qian, Mirco Troue, Johannes Figueiredo +8
We report lasing of moiré trapped interlayer excitons (IXs) by integrating a pristine hBN-encapsulated MoSe/WSe heterobilayer into a high- () nanophotonic cavity.…
Hyperfine-interaction limits polarization entanglement of photons from semiconductor quantum dots
Christian Schimpf, Francesco Basso Basset, Maximilian Aigner +12
Excitons in quantum dots are excellent sources of polarization-entangled photon pairs, but a quantitative understanding of their interaction with the nuclear spin bath is still mis…
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…
Magneto-optics of a charge-tunable quantum dot: Observation of a negative diamagnetic shift
Giora Peniakov, Ayal Beck, Eilon Poem +5
We present magneto-optical studies of a self-assembled semiconductor quantum dot in neutral and positively charged states. The diamagnetic shifts and Zeeman splitting of many well-…
