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…
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…
Coherent Free-Space Optical Communications with Concurrent Turbulence Characterization in a Terrestrial Urban Link
Vincent van Vliet, Menno van den Hout, Kadir GümüŠ+2
We present a 19-day joint measurement of optical turbulence and coherent data communications over a 4.6 km urban FSO link, providing empirical insights into turbulence effects on t…
Short Blocklength Error Correction Codes for Continuous-Variable Quantum Key Distribution
Kadir GümüÅ, João dos Reis Frazão, Boris Å koriÄ +4
We introduce a two-step error correction scheme for reconciliation in continuous-variable quantum key distribution systems. Using this scheme, it is possible to use error correctio…
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 GümüŠ+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…
