  • Efficient electro-optic conversion is central to photonic computing, and thin-film lithium niobate (TFLN) offers this capability. Here, the authors demonstrate computing circuits on the TFLN platform, enabling the next generation of photonic computing systems featuring both high-speed and low-power.

  • By leveraging microcavity-integrated photonics and Kerr-induced optical frequency division, an integrated photonic millimetre-wave oscillator with low phase noise is demonstrated, achieving –77 dBc Hz–1 and –121 dBc Hz–1, respectively, at 100-Hz and 10-kHz offset frequencies, corresponding to –98 dBc Hz–1 and –142 dBc Hz–1 when scaled to a 10-GHz carrier.

  • A monolithically grown Ge/Si avalanche photodetectors (APD) with a gain–bandwidth product of 340 GHz, the highest value for any APDs operating at 1,300 nm, and a sensitivity equivalent to commercially available III-V compound APDs is reported. The excellent performance paves the way to achieving low-cost, CMOS-based, Ge/Si APDs operating at data rates of 40 Gb s−1 or higher, where the performance of III-V APDs is severely limited.

  • A miniaturized optical frequency division system that could transfer the generation of microwaves, with superior spectral purity, to a complementary metal-oxide-semiconductor-compatible integrated photonic platform is demonstrated showing potential for large-volume, low-cost manufacturing for many applications.
