Emission of electromagnetic waves is expected when superconducting vortices cross sample edges, but such a radiation has not been observed so far. Here, Dobrovolskiy et al. evidence the electromagnetic radiation from vortices crossing the layers of a Mo/Si superlattice, where the emission spectra can be tuned by dc bias current and coarsely by the in-plane magnetic field.
