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…
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…
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…
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…
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…
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…
3D-printed axicon enables extended depth-of-focus intravascular optical coherence tomography
Pavel Ruchka, Alok Kushwaha, Jessica A. Marathe +12
A fundamental challenge in endoscopy is how to fabricate a small fiber-optic probe that can achieve comparable function to probes with large, complicated optics (e.g., high resolut…
Microscopic 3D printed optical tweezers for atomic quantum technology
Pavel Ruchka, Sina Hammer, Marian Rockenhäuser +5
Trapping of single ultracold atoms is an important tool for applications ranging from quantum computation and communication to sensing. However, most experimental setups, while ver…
