Novel Optical Field Reconstruction for IM/DD with Receiver Bandwidth Well Below Full Optical Signal Bandwidth
08 March 2020
We propose a novel signal reception scheme for IM/DD enabling optical field reconstruction. We experimentally demonstrate 60-GBd PAM-4 transmission over 80-km with 33-GHz electrical bandwidth at both transmitter and receiver, without optical filtering, optical dispersion compensation, nor optical amplification, allowing for 20-fold transmission distance.
