Figure | Hybrid Kerr-electro-optic frequency comb on thin-film lithium niobate. a, 3-D illustration of the hybrid Kerr-EO frequency comb using both Z-cut and X-cut TFLN, consisting of a DKS microresonator chip and an EO phase modulator chip, respectively. b, Schematic of the hybrid Kerr-EO frequency comb generation process. A DKS frequency comb (blue) serves as the source, and comb line generates EO sidebands (red) around it at multiples of the microwave modulation frequency. The final output of the hybrid comb generator consists of both blue and red lines. c, Electro-optically modulated single DKS spectrum, featuring 2,589 comb lines spaced by 29.308 GHz and spanning 75.9 THz.
