Abstract:
We propose the first 5-dimensional coherent receiver leveraging a DSB- or SSB-modulated remote local oscillator and digital field reconstruction. We experimentally demonstrate single-channel net 1.2-Tb/s PS-256-QAM signal 25-km single-mode fiber transmission within only 47.5-GHz electrical bandwidth, achieving a 25.3-b/s/Hz net electrical spectral efficiency.
