The short de Broglie wavelength and strong interaction empower free electrons to probe structures excitations in materials biomolecules. Recently, electron-photon interactions have enabled new optical manipulation schemes for electron beams. In this work, we demonstrate the of with nonlinear states inside a photonic chip–based microresonator. Optical parametric processes give rise spatiotemporal pattern formation corresponding coherent or incoherent frequency combs. We couple such “microcombs” beams, their fingerprints spectra, achieve ultrafast temporal gating beam. Our work demonstrates ability access solitons an microscope extends use microcombs control imaging spectroscopy.
