Co-propagation of Classical and Continuous-variable QKD Signals over a Turbulent Optical Channel with a Real-time QKD Receiver
João dos Reis Frazão, Vincent van Vliet, Sjoerd van der Heide +5
We demonstrate classical and quantum signal co-propagation over a turbulent free-space channel with 3 Tbit/s throughput and record 2.7 Mbit/s secret-key rate. Our real-time GPU-bas…
Experimental Investigation of Mode Diversity Reception Using an Optical Turbulence Generator and Digital Holography
Vincent van Vliet, Menno van den Hout, Sjoerd van der Heide +1
Mode diversity reception is experimentally investigated using an optical turbulence generator, off-axis digital holography, and digital demultiplexing. The results confirm improved…
Alignment of Free-Space Coupling of Few-Mode Fibre to Multi-Mode Fibre using Digital Holography
Menno van den Hout, Sjoerd van der Heide, Thomas Bradley +11
Off-axis digital holography is used to align a few-mode fiber to a multi-mode fiber in a free-space optical setup. Alignment based on power coupling measurements alone cannot guara…
On Optimum Enumerative Sphere Shaping Blocklength at Different Symbol Rates for the Nonlinear Fiber Channel
Yunus Can Gültekin, Olga Vassilieva, Inwoong Kim +3
We show that a 0.9 dB SNR improvement can be obtained via short-blocklength enumerative sphere shaping for single-span transmission at 56 GBd. This gain vanishes for higher symbol…
High-Cardinality Hybrid Shaping for 4D Modulation Formats in Optical Communications Optimized via End-to-End Learning
Vinícius Oliari, Boris Karanov, Sebastiaan Goossens +6
In this paper we carry out a joint optimization of probabilistic (PS) and geometric shaping (GS) for four-dimensional (4D) modulation formats in long-haul coherent wavelength divis…
