Optical solitons have been produced —light waves that retain their shape—using a microresonator. By adapting the parameters for manufacturing microresonators, the EPFL researchers additionally managed to generate a so-called soliton Cherenkov radiation. This broadens the frequency spectrum: the comb contains a greater number of teeth. Published in Science, the results have set a new record for this type of structure.
