Abstract :
We report on a 4-channel radio-frequency arbitrary waveform generator, capable to switch within a clock period among synthesized radio-frequency arbitrary waveforms. The system works by combining an original switching scheme of time-multiplexed multi-wavelength optical frequency combs with a two-dimensional line-by-line pulse shaper featuring broad bandwidth operation over large temporal windows. By going to finer pulse shaper resolution, the number of channels can be scaled up while keeping the same number of optoelectronic components.
