Successive Eigenvalue Removal for Multi-Soliton Spectral Amplitude Estimation
Alexander Span, Vahid Aref, Henning Buelow +1
Optical nonlinear Fourier transform-based communication systems require an accurate estimation of a signal's nonlinear spectrum, computed usually by piecewise approximation methods…
Time-Bandwidth Product Perspective for Multi-Soliton Phase Modulation
Alexander Span, Vahid Aref, Henning Buelow +1
Multi-soliton pulses are potential candidates for fiber optical transmission where the information is modulated and recovered in the so-called nonlinear Fourier domain. While this…
Efficient Precoding Scheme for Dual-Polarization Multi-Soliton Spectral Amplitude Modulation
Alexander Span, Vahid Aref, Henning Buelow +1
Spectral amplitude modulation for dual-polarization multi-soliton transmission is considered. We show, that spectral amplitudes become highly correlated during propagation along a…
An Efficient Nonlinear Fourier Transform Algorithm for Detection of Eigenvalues from Continuous Spectrum
Vahid Aref, Son T. Le, Henning Buelow
We present an efficient, fast and robust Nonlinear Fourier Transform (NFT) algorithm to detect eigenvalues of the discrete spectrum. It outperforms other known NFT algorithms as it…
End-to-end Deep Learning of Optical Fiber Communications
Boris Karanov, Mathieu Chagnon, Félix Thouin +5
In this paper, we implement an optical fiber communication system as an end-to-end deep neural network, including the complete chain of transmitter, channel model, and receiver. Th…
Does the Cross-Talk Between Nonlinear Modes Limit the Performance of NFDM Systems?
Vahid Aref, Son T. Le, Henning Buelow
We show a non-negligible cross-talk between nonlinear modes in Nonlinear Frequency-Division Multiplexed system when data is modulated over the nonlinear Fourier spectrum, both the…
Applying Neural Networks in Optical Communication Systems: Possible Pitfalls
Tobias A. Eriksson, Henning Bülow, Andreas Leven
We investigate the risk of overestimating the performance gain when applying neural network based receivers in systems with pseudo random bit sequences or with limited memory depth…
Design Aspects of Multi-Soliton Pulses for Optical Fiber Transmission
Vahid Aref, Zhenhua Dong, Henning Buelow
We explain how to optimize the nonlinear spectrum of multi-soliton pulses by considering the practical constraints of transmitter, receiver, and lumped-amplified link. The optimiza…
Demonstration of Fully Nonlinear Spectrum Modulated System in the Highly Nonlinear Optical Transmission Regime
Vahid Aref, Son T. Le, Henning Buelow
We report a 3 dB increase in the nonlinear threshold of a 64*0.5Gbaud 16-QAM continuous-nonlinear-spectrum modulated signal by nonlinear multiplexing with QPSK modulated multi-soli…
Transmission of Waveforms Determined by 7 Eigenvalues with PSK-Modulated Spectral Amplitudes
Henning Buelow, Vahid Aref, Wilfried Idler
2-ns waveforms with 7 eigenvalues and their QPSK-modulated spectral amplitudes were optimized by taking constraints of link, transmitter, and receiver into account. In experiment t…
