Multichannel Radio-Frequency Arbitrary Waveform Generation Based on Multiwavelength Comb Switching and 2-D Line-by-Line Pulse Shaping

摘要

We demonstrate a multichannel time-multiplexedradio-frequency arbitrary waveform generator. The system combines a switching scheme of multiwavelength optical frequencycombs with a novel 2-D line-by-line pulse shaper featuring broadbandwidth operation over large temporal windows. Switchingtimes within a clock period of 200 ps among the four channelsis successfully achieved. With finer pulse shaper resolution, thenumber of channels can be scaled up without increasing thenumber of switching components.
