Single-photodiode 100 Gbaud PAM-6 Transmission with Extended Transmitter Bandwidth using Optical Time and Polarization Interleaving

We demonstrate an optical time and polarization interleaving (OTPI) technique to extend the transmitter bandwidth. Using a single photodiode, 25-GHz DACs and modulators, 100 Gbaud OTPI-PAM-6 signals have been transmitted over 1 km NZDSF.
