Characterising Interleaver Length in a Turbulent Deployed Terrestrial Free-Space Optical Link
Kadir Gümüş, Vincent van Vliet, Menno van den Hout +3
We investigate the correlation between interleaver length and turbulence for a deployed terrestrial free-space optical link spanning 4.6 km. Using 24 hours of measurements, we show…
Mitigating Outages in a 4.6-km FSO Link via Mode-Diverse Reception: An Experimentally Validated Digital Twin Approach
Jonas Krimmer, Vincent van Vliet, Menno van den Hout +3
Terrestrial coherent FSO requires mitigating turbulence-induced coupling losses. We experimentally validate a "Digital Twin" channel model against fading statistics from a 4.6-km l…
Reducing Turbulence-Induced Outages in a Deployed Terrestrial Free-Space Optical Communication Link via Interleaving
Kadir GümüÅ, Vincent van Vliet, Menno van den Hout +3
We present an experimental study of data interleaving for terrestrial free-space optical communication over a 4.6~km urban testbed. Results demonstrate a two-order-of-magnitude red…
Compact Continuous-Variable Quantum Key Distribution System Employing Monolithically Integrated Silicon Photonic Transceiver
Denis Fatkhiev, João dos Reis Frazão, Alireza H. Derkani +4
We demonstrate the first CV-QKD system featuring a custom-designed monolithic silicon photonic dual-polarisation transceiver. Leveraging PS-64-QAM, we achieved 1.9 Mbit/s secret ke…
High-Capacity Urban Terrestrial Free-Space Optical Communication Links at km-Scale
Vincent van Vliet, Menno van den Hout, Eduward Tangdiongga +1
Free-space optical communication links can enable high-capacity wireless connectivity in urban areas. We discuss the feasibility, challenges, and recent developments for high-capac…
On Irradiance Distributions for Weakly Turbulent FSO Links: Log-Normal vs. Gamma-Gamma
Carmen Ãlvarez Roa, Yunus Can Gültekin, Vincent van Vliet +3
Weak turbulence is commonly modeled using the log-normal distribution. Our experimental results show that this distribution fails to capture irradiance fluctuations in this regime.…
