Abstract Metasurfaces can manipulate the amplitude and phase of electromagnetic waves, offering applications from antenna design and cloaking to imaging and communication. Temporal and non-linear metasurfaces can also adjust the frequency of impinging waves, advancing frequency conversion, sensing, and quantum systems. Here, we demonstrate a non-linear active electronic-photonic metasurface that transfers information from an impinging optical wave to a millimeter-wave beam.

Implementing stable lasers often requires complex packaging of multiple devices, such as stand-alone external cavities and isolators. Now, stabilizing and isolating lasers can be realized in a single silicon chip thanks to the Kerr nonlinear effect in a resonator.
