Abstract

Integrated photonics is becoming more and more multifunctional thanks to the recent availability of an established material, lithium niobate, as thin films of less than 1 micron thickness. Overcoming key fabrication challenges has put this platform on its way to achieve scalability. Here, we show the performances of integrated and free space devices such as electrooptic modulators and active metasurfaces. Finally, we mention possible roles of lithium niobate on insulator in quantum photonics.
