Fig. 2: Characteristics of measured chaotic microcomb.
From: Scalable parallel ultrafast optical random bit generation based on a single chaotic microcomb
a Optical spectrum of the chaotic microcomb, where the blue shaded areas indicate the comb lines used for parallel random bit generation. b Optical spectrum, c temporal waveform, d radio-frequency spectrum, and e autocorrelation function of a single comb-line in the blue shadow. Note, the red dashed circles represent the frequency components for flat chaos generation in Fig. 2b
