Non-Cubic Eightfold Constellation for High-Performance Stokes Vector Modulation

https://doi.org/10.1364/FIO.2022.JTu7A.3

Feuer, Mark D. ; Bnyamin, Mario V. ; Jiang, Xin ( October 2022 , Optica Publishing Group)

A novel non-cubic constellation for eightfold Stokes vector modulation improves modulation loss, link budget, and intersymbol interference at high speed, while using simpler drive signals. Experiments confirm 5.2 dB improvement at 30 Gb/s.

Independent Component Analysis Equalizer for Direct Detection in Presence of Modal and Temporal Crosstalk

Bnyamin, Mario V. ; Jiang, Xin ; Feuer, Mark D. ( January 2022 , Advanced Photonics Congress – Signal Processing in Photonic Communications 2022)

Abstract: A novel adaptation of independent component analysis controls both cross-polarization and inter-symbol interference in a direct-detection link using Stokes vector modulation. 30-Gb/s experiments confirm polarization de-rotation and near-error-free transmission.
