Fig. 5: Spectral coherence of microcombs.
Gray scatter plots show the visibility calculated at each comb line as a measure of spectral coherence70, to characterize microcomb shapes located by the genetic algorithm at a–c 20 ps delay (~0τph), d–f 5 ns delay (~1τph), and g–i15 ns (~3τph), respectively, for each presented microcomb state. Each panel is also labelled with the average visibility value \(\bar{V}\) as an inset.
