Abstract

We demonstrate a simultaneous generation of wavelength-division-multiplexed chirped microwave waveforms using an optical spectral shaping followed by a wavelength-to-time mapping. We design two types of integrated spectral shapers based on parallel distributed Fabry–Pérot cavities or an arrayed waveguide grating Sagnac interferometer incorporating linearly chirped waveguide Bragg gratings. The generated waveforms have different central RF frequencies and the opposite signs of RF chirp.
