Exploring and Experimenting with Shaping Designs for Next-Generation Optical Communications
Fanny Jardel, Tobias A. Eriksson, Cyril Méasson +4
A class of circular 64-QAM that combines 'geometric' and 'probabilistic' shaping aspects is presented. It is compared to square 64-QAM in back-to-back, single-channel, and WDM tran…

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…
