文摘

We provide an overview of photonic generation of chirped microwave and millimeter wave pulses based on optical spectral shaping followed by wavelength-to-time mapping. We summarize results obtained using bulk optic/benchtop and all-fiber spectral shapers, and discuss recent developments on integrated versions in silicon photonics. In particular, we describe devices based on microring resonators and present new results obtained using integrated spectral shapers incorporating chirped Bragg gratings.
