Parallel random bit generation with a chaotic micro-comb.

Caption

a. experimental schematic. TL, tunable laser; EDFA, erbium-doped fiber amplifier; PC, polarization controller; DEMUX, optical demultiplexer; PD, photodetector; ADC, 16-bit analog-to-digital converter; MRR, micro-ring resonator. Note, the dash box contains a microscope image of a high-index doped silica glass MRR with a radius of ~ 592.1 μm. b. Optical spectrum of the chaotic microcomb. c. Temporal waveforms of the chaotic comb-lines (parallel chaos). d. Cross-correlation function between any two channels of parallel chaos. e. XOR bitmap image between any two extracted binary sequences from parallel chaos.
