Integrated photonics has proven to facilitate the interaction of light with free electrons in electron microscopy by significantly boosting the coupling strength. This enables the exploration of quantum optics with free electrons as well as a probing of nonlinear optical effects inherent to integrated microresonators with electron spectroscopy.
Here, we harness the inelastic electron-light scattering to investigate the spatial and spectral properties of the electric field inside a high-Q silicon nitride microresonator. For increasing optical input powers, characteristic changes to the electron energy spectra that coincide with the formation of various nonlinear intracavity states including dissipative Kerr solitons are observed.
In the future, this enables new schemes in electron beam modulation and manipulation, while electron-based optical state probing may also be extended to different quantum states of light.
