Observation of dispersive-wave emission by temporal cavity solitons

Here we report, for the first time to our knowledge, direct experimental observations of dispersive wave (DW) emission by temporal cavity solitons (CSs). We expect that a better understanding of this process will lead to larger Kerr frequency comb bandwidths akin to what has been achieved in supercontinuum generation, and thereby our study has strong practical implications for the many technological and scientific applications of Kerr combs.
