Paper: "100G FSO Transmission Using 3-Bit DAC and Self-Coherent Detection"

-

 The paper "100G FSO Transmission Using 3-Bit DAC and Self-Coherent Detection" was accepted for the oral presentation at the OFC 2023 conference, which will be held between 5 - 9 March 2023 in San Diego, California, USA.

The paper presents the demonstration of a net 100 Gbps transmission over a 42 m free space optics (FSO) link using a 3-bit digital-to-analog converter (DAC) and virtual carrier-assisted self-coherent detection. The error-free transmission using such an ultra-low resolution DAC is made possible by employing the digital resolution enhancer (DRE) method. Thus, the technique presented in the article significantly contributes to lowering the commercial entry barrier of high-capacity FSO systems.

The event "QKD days in Madrid" brought together leading QKD experts, as well as European equipment suppliers and policymakers on 14 and 15 December 2022. Sponsored by the QuantaGENOMICS’ partner Universidad Politécnica de Madrid, in collaboration with the Austrian Institute of Technology, and Telefónica, Madrid, the event was an opportunity to join contributions from companies, universities, and researchers from 38 members of a European consortium of the Quantum Flagship to pave the way towards a pan-European infrastructure for secure quantum communication (QKD, Quantum Key Distribution, cryptographic networks). The first of the QKD Days 2022, entitled "On the Road, Large QKD Networks in Europe”, the EuroQCI initiative of the European Commission was presented. Other speakers included: Johanna Sepúlveda (Airbus Defence and Space) and Felix Wissel (Deutsche Telekom).  Under the title "QKD Industry Day", the second day had noteworthy presentations and highlighted...

Secure Communication Link  connecting two points, on a 14-kilometer route, in Lisbon. FCCN, IPTelecom and Warpcom, partners in the Portuguese Quantum Communications Infrastructure – PTQCI project, joined forces to implement a modern secure communications link, through a system that combines a quantum cryptographic technology with network and security solutions, connecting two points, on a 14-kilometer route, in Lisbon. A Quantum Key Distribution (QKD) system was used to perform the activity, with the purpose of guaranteeing the security of the generation of cipher keys between two points. The exercise highlights the importance of the technology for data protection and encryption and for strengthening the communication infrastructure in Portugal. “This demonstration is not only evidence of technological progress but also a materialization of collaborative innovation. It demonstrates what can be developed when experts in the field come together to open new frontiers in data security ...
