On Irradiance Distributions for Weakly Turbulent FSO Links: Log-Normal vs. Gamma-Gamma
Carmen Álvarez 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.…
Experimental Investigation of Availability in a 4.6 km Terrestrial Urban Coherent Free-Space Optical Communications Link
Vincent van Vliet, Menno van den Hout, Kadir Gümüş +2
We measured the outage probability of a 4.6-km urban free-space optical communication link over six days. High-speed power measurements reveal slow and fast fading effects, with li…
Early Termination of Low-Density Parity-Check Codes for Continuous-Variable Quantum Key Distribution
Kadir Gümüş, João dos Reis Frazão, Vincent van Vliet +4
We analyse the impact of log a-posteriori early termination on the decoding throughput of reconciliation for continuous-variable quantum key distribution. Increases in decoded secr…
Mitigation of Polarization-Induced Fading in Optical Vector Network Analyzer for the Characterization of km-scale Space-Division Multiplexing Fibers
Besma Kalla, Martina Cappelletti, Menno van den Hout +5
We propose an optimized optical vector network analyzer with automatic polarization control to stabilize the reference arm polarization throughout the sweep range. We demonstrate t…
