Near-zero-dispersion soliton microcombs with tightly bound temporal structures. (IMAGE)
Caption
(a) Experimentally obtained microcomb spectra at different NZDS states, along with the spectrum simulation results (orange curve). The dispersive waves are marked by red arrows in (a). The corresponding temporal simulation results are presented in (b). which are made up of a series of interconnecting individual soliton structures. The number of bound solitons provides a noticeable feature for distinguishing different NZDS states. The NZDS microcomb has the advantage of producing dense soliton cluster with a local repetition frequency up to 8.6 THz and an individual pulse duration less than 100 fs. This unique temporal structure will extend the application potential of Kerr soliton in optical computation, signal processing, and sensing.
