6-Dimensional Coherent Receiver with IQ Modulated LO
We propose a 6-dimensional coherent receiver with IQ-modulated remote LO. We experimentally demonstrate single-channel 2.5-Tb/s line rate PS-256-QAM signal transmission over 25-km SSMF within 67.6-GHz electrical bandwidth, achieving net electrical spectral efficiency of 29.1 b/s/Hz.
