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…
4D Geometric Shell Shaping with Applications to 400ZR
Sebastiaan Goossens, Yunus Can Gültekin, Olga Vassilieva +4
Geometric shell shaping is introduced and evaluated for reach increase and nonlinearity tolerance in terms of MI against PM-16QAM and PS-PM-16QAM in a 400ZR compatible transmission…
Introducing 4D Geometric Shell Shaping for Mitigating Nonlinear Interference Noise
Sebastiaan Goossens, Yunus Can Gültekin, Olga Vassilieva +4
Four dimensional geometric shell shaping (4D-GSS) is introduced as an approach for closing the nonlinearity-caused shaping gap. This format is designed at the spectral efficiency o…
Experimental Validation of Sequence-Wise Predistorter for Evaluation of Geometrically Shaped 128-QAM
Menno van den Hout, Sjoerd van der Heide, Sebastiaan Goossens +1
A predistorter for transmitter nonlinearities is applied to the evaluation of a geometrically shaped constellation, such that constellation points are transmitted correctly during…
Optical Field Characterization using Off-axis Digital Holography
Sjoerd van der Heide, Bram van Esch, Menno van den Hout +10
Angular resolved digital holography is presented as a technique for real-time characterization of the full optical field (amplitude and phase) of space-division multiplexing compon…
Mitigating Nonlinear Interference by Limiting Energy Variations in Sphere Shaping
Yunus Can Gültekin, Alex Alvarado, Olga Vassilieva +4
Band-trellis enumerative sphere shaping is proposed to decrease the energy variations in channel input sequences. Against sphere shaping, 0.74 dB SNR gain and up to 9% increase in…
