Time-multiplexed photonically enabled radio-frequency arbitrary waveform generation with 100 ps transitions.

For the first time, to our knowledge, radio-frequency arbitrary waveforms are time-multiplexed within 100 ps by integrating wavelength switching, optical frequency comb generation, and spectral line-by-line shaping. The novel time-multiplexed scheme demonstrated here can be extended to wide user specifications and faster waveform transition time.
