Integrated thin-film lithium niobate (TFLN) photonics is a promising platform for high-performance chip-scale optical systems. By integrating high-power lasers and modulators, we have achieved a high-power transmitter on the TFLN chip.
Integrated thin-film lithium niobate (TFLN) photonics has emerged as a promising platform for the realization of high-performance chip-scale optical systems. Of particular importance are TFLN electro-optic modulators featuring high-linearity, low driving voltage and low propagation loss. However, a fully integrated system requires integration of high power, low noise, and narrow linewidth lasers on TFLN chips. Here 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 of an electrically pumped laser integrated with a 50 GHz modulator.
