Single-Channel Direct Detection Reception Beyond 1 Tb/s

We demonstrate the world-first single-channel direct detection beyond 1-Tb/s with 1.26-Tb/s line rate and 1.02-Tb/s net rate after 100-km SSMF, via an 86-GHz Stokes vector receiver that recovers totally single-polarization-equivalent 252-Gbaud probabilistic-shaped 64-QAM signal.
