Abstract

We demonstrate high-fidelity optical arbitrary waveform generation with 5GHz waveform switching via time-domain multiplexing. Compact, integrated waveform shapers based on silica arrayed-waveguide grating pairs with 10GHz channel spacing are used to shape (line-by-line) two different waveforms from the output of a 10-mode×10GHz optical frequency comb generator. Characterization of the time multiplexer’s complex transfer function (amplitude and phase) by frequency-resolved optical gating permits compensation of its impact on the switched waveforms and matching of the measured and target waveforms to better than G=5%.
