Development of a scintillator based fast-ion loss detector for the Wendelstein 7-X stellarator
A new scintillator based fast -ion loss detector (FILD) system has been designed for the Wendelstein 7-X (W7X) stellarator. The mechanical design of the system is presented here along with engineering analyses of the system. This includes an assessment of ...
2024A fully hybrid integrated erbium-based laser
Tobias Kippenberg, Rui Ning Wang, Andrey Voloshin, Xinru Ji, Zheru Qiu, Andrea Bancora, Yang Liu
Erbium-doped fibre lasers exhibit high coherence and low noise as required for fibre-optic sensing, gyroscopes, LiDAR and optical frequency metrology. Endowing erbium-based gain in photonic integrated circuits can provide a basis for miniaturizing low-nois ...
Nature Portfolio2024Precoding for High-Throughput Satellite Communication Systems: A Survey
With the expanding demand for high data rates and extensive coverage, high throughput satellite (HTS) communication systems are emerging as a key technology for future communication generations. However, current frequency bands are increasingly congested. ...
Ieee-Inst Electrical Electronics Engineers Inc2024Privatized graph federated learning
Ali H. Sayed, Stefan Vlaski, Elsa Rizk
Federated learning is a semi-distributed algorithm, where a server communicates with multiple dispersed clients to learn a global model. The federated architecture is not robust and is sensitive to communication and computational overloads due to its one-m ...

Centralized and cloud computing-based network architectures are the promising tracks of future communication systems where a large scale compute power can be virtualized for various algorithms. These architectures rely on high-performance communication lin ...
IEEE2021Drone-aided Localization in LoRa IoT Networks
Dario Floreano, Alexandru Rusu, Fabrizio Schiano, Giuseppe Cocco
Besides being part of the Internet of Things (IoT), drones can play a relevant role in it as enablers. The 3D mobility of UAVs can be exploited to improve node localization in IoT networks for, e.g., search and rescue or goods localization and tracking. On ...
2020On the assessment of aspheric refractive microlenses
Refractive microlenses and microlens arrays are key components for many applications such as optical data communication, laser and medical devices, or cameras. In particular, refractive micro-optics enables the miniaturization of high-tech systems but also ...
EPFL2020Physical Layer Aspects of LoRa and Full-Duplex Wireless Transceivers
Wireless communications are currently faced with two main challenges. The first challenge stems from the enormous number of Internet of Things (IoT) devices that transmit very small amounts of data. The second challenge is the need for ever-increasing data ...
