Abstract
Chip-scale electro-optic (EO) frequency combs are expected to play
an essential role in future high-capacity optical communications systems
and next-generation mobile communications. The application requires
integrated EO frequency comb generators featuring good spectral flatness,
high modulation bandwidth, low driving voltage and low insertion loss
simultaneously. Here, we demonstrate a flat-top optical flat comb (OFC)
generator based on high-performance lithium niobate on insulator
modulators. The OFC generator shows a low on-chip loss (2.1 dB), a low
driving voltage over a broad frequency range, and a large 3-dB EO
bandwidth. Moreover, with consuming power of less than 2W, the presented
device produces 13 lines with a power variation of less than 1.2 dB and a
line spacing of 31 GHz which can further be extended to 67 GHz.
