Experimental Validation of Sequence-Wise Predistorter for Evaluation of Geometrically Shaped 128-QAM
A predistorter for transmitter nonlinearities is applied to the evaluation of a geometrically shaped constellation, such that constellation points are transmitted correctly during the evaluation of the geometrically shaped constellation.
MDG and SNR Estimation in SDM Transmission Based on Artificial Neural Networks
In a recent work we propose an MDG and SNR estimation method using ANN.
Kramers-Kronig Receiver Combined With Digital Resolution Enhancer
A Kramers-Kronig receiver with a continuous wave tone added digitally at the transmitter is combined with a digital resolution enhancer to limit the increase in transmitter quantization noise.
Neural-network-based MDG and Optical SNR Estimation in SDM Transmission
We propose a neural network model for MDG and optical SNR estimation in SDM transmission.
Experimental validation of MDL emulation and estimation techniques for SDM transmission systems
We experimentally validate a mode-dependent loss (MDL) estimation technique employing acorrection factor to remove the MDL estimation dependence on the SNR when using a minimum meansquare error (MMSE) equalizer.
1 Tbit/s/$λ$ Transmission Over a 130 km Link Consisting of Graded-Index 50 $μ$m Core Multi-Mode Fiber and 6LP Few-Mode Fiber
We demonstrate 1 Tbit/s/$\lambda$ single-span transmission over a heterogeneous link consisting of graded-index 50 $\mu$m core multi-mode fiber and 6LP few-mode fiber using a Kramers-Kronig receiver structure.

Exploiting Angular Multiplexing for Polarization-diversity in Off-axis Digital Holography
Digital holography measures the complex optical field and transfer matrix of a device, polarization-diversity is often achieved through spatial multiplexing.
Mode-dependent Loss and Gain Estimation in SDM Transmission Based on MMSE Equalizers
Based on the transfer function of MIMO MMSE equalizers, and assuming a known SNR, we calculate a correction factor that improves the estimation process in moderate levels of MDL/MDG and SNR.
Revisiting Efficient Multi-Step Nonlinearity Compensation with Machine Learning: An Experimental Demonstration
One guiding principle for previous work on the design of practical nonlinearity compensation schemes is that fewer steps lead to better systems.
Analysis and Experimental Demonstration of Orthant-Symmetric Four-dimensional 7 bit/4D-sym Modulation for Optical Fiber Communication
We propose a new four-dimensional orthant-symmetric 128-ary modulation format (4D-OS128) with a spectral efficiency of 7bit/4D-sym.
