Integrated thin-film lithium niobate (TFLN) photonics has emerged as a promising platform for realization of high-performance chip-scale optical systems. It provides the opportunity to achieve fully integrated photonic system that contains laser, modulator, detector, etc.

High power laser integrated on thin-film lithium niobate [Amirhassan Shams-Ansari, et al. arXiv: 2111.08473 (2021)]: we achieve this goal, and demonstrate integrated high-power lasers on TFLN platform with up to 60 mW of optical power in the waveguides. We use this platform to realize a high-power transmitter consisting an electrically-pumped laser integrated with a 50 GHz modulator.
