We implement an optical arbitrary-waveform generator (OAWG) that relies on spectrally
sliced signal synthesis with well-defined feedback-stabilized phase relations. We
demonstrate the viability of the approach by generating high-quality 16QAM signals with
record-high symbol rates of up to 200 GBd.
Abstract
We implement an optical arbitrary-waveform generator (OAWG) that relies on spectrally sliced signal synthesis with well-defined feedback-stabilized phase relations. We demonstrate the viability of the approach by generating high-quality 16QAM signals with record-high symbol rates of up to 200 GBd.
