Optical Arbitrary Waveform Generation (OAWG) Using Actively Phase-Stabilized Spectral Stitching
Daniel Drayss, Dengyang Fang, Alban Sherifaj +10
The conventional way of generating optical waveforms relies on the in-phase and quadrature (IQ) modulation of a continuous wave (CW) laser tone. In this case, the bandwidth of the…

First Single-Carrier Transmission at Net Data Rates of 1.6 Tb/s over 9075 km and 2.4 Tb/s over 1210 km Using 300 GBd Dual-Polarization Signals and Probabilistic Constellation Shaping
Haik Mardoyan, Daniel Drayss, Sylvain Almonacil +7
We report long-haul transmissions of single-carrier 300 GBd dual-polarization signals with optical arbitrary waveform generation and measurement. We demonstrate net 1.6 Tb/s over 9…
