Resolving High-Energy States of Interlayer Excitons in MoSe/WSe Heterostructures
Chirag Chandrakant Palekar, Paulo E. Faria Junior, Tobias Manthei +8
High-energy states of interlayer excitons (IXs) in van der Waals heterostructures remain largely unexplored despite their importance for understanding many-body interactions and no…
An integrated all-van der Waals nanobeam laser
Aris Koulas-Simos, Pietro Metuh, Athanasios Paralikis +7
Transition-metal dichalcogenides offer a promising platform for integrated coherent light sources, yet lasing has largely relied on hybrid photonic architectures without direct qua…
Anisotropic nanoscale coherent polariton transport in CrSBr
Paritosh Malik, Dogyun Ko, Vita Solovyeva +11
In a combined experimental and theoretical study, we demonstrate anisotropic polariton transport on the nanoscale in the van der Waals antiferromagnet CrSBr. While effective cavity…
Energy-time entanglement from a monolithically integrated quantum dot on silicon
Marcel Hohn, Imad Limame, Peter Ludewig +4
Scalable quantum photonic technologies require deterministic sources of entangled photons that are compatible with established semiconductor manufacturing platforms. While self-ass…
Integrated Whispering-Gallery Microlaser-Waveguide Platform for On-Chip Electrical Excitation of InGaAs Quantum Dots
Léo J. Roche, Peter Gschwandtner, Chirag C. Palekar +6
We report the fabrication and characterization of an integrated quantum photonic device consisting of an electrically driven whispering-gallery-mode micropillar laser evanescently…
Monolithic axial InGaAs quantum dot emitters in GaAs-based nanowires via Sb-mediated facet engineering
Hyowon W. Jeong, Aris Koulas-Simos, Imad Limame +6
GaAs-based nanowires hosting active quantum heterostructures provide a promising route toward monolithic integration of single-photon sources on silicon, a key requirement for scal…
