Compact system development of efficient quantum-entangled photon sources towards deployable and industrial devices
Yared G. Zena, Moritz Langer, Ahmad Rahimi +9
Entangled photon pair sources are a key enabling technology for quantum communication and networking, yet their deployment beyond laboratory environments is hindered by system-leve…
Compact vacuum levitation and control platform with a single 3D-printed fiber lens
Seyed Khalil Alavi, Jose Manuel Monterrosas Romero, Pavel Ruchka +3
Levitated dielectric particles in a vacuum have emerged as a new platform in quantum science, with applications ranging from precision acceleration and force sensing to testing qua…
A Multi-Dimensional Cathodoluminescence Detector with 3D Printed Micro-Optics on a Fiber
Paul H. Bittorf, Filip Majstorovic, Pavel Ruchka +2
Cathodoluminescence, i.e. the radiation caused by the interaction of high-energy electron beams with matter, has gained a major interest in the analysis of minerals, semiconductors…
Exciton Energy Routing via Defect Networks in hBN/2D-Perovskite Hybrids
Sara Darbari, Paul Bittorf, Leon Multerer +7
Excitons in two dimensional Ruddlesden Popper perovskites (RPPs) exhibit large and tunable binding energies, making them promising candidates for optoelectronic applications. In pa…
Efficient fiber coupling of telecom single-photons from circular Bragg gratings
Nam Tran, Pavel Ruchka, Sara Jakovljevic +9
Deterministic sources of quantum light are becoming increasingly relevant in the development of quantum communication, particularly in deployed fiber networks. Therefore, efficient…
An ultra-compact deterministic source of maximally entangled photon pairs
M. Langer, P. Ruchka, A. Rahimi +9
We present an ultra-compact source of maximally entangled on-demand photon pairs. Our results are based on coupling of single GaAs quantum dots that are embedded in monolithic micr…
