Our approach exploits synthetic frequency lattices with pump-induced spectral short- and long-range couplings between different signal components across a broad bandwidth of hundreds of GHz in a single nonlinear fiber. When combined with ultra-fast signal conversion techniques, this approach has the potential to provide real-time measurement of pulse-to-pulse variations in the spectral phase and coherence properties of exotic light sources.application/pdfen-AU© 2020 Author(s).http://creativecommons.org/licenses/by/4.0/Synthetic photonic lattice for single-shot reconstruction of frequency combs202010.1063/1.51441192021-08-01Creative Commons Attribution License
