New photonic integrated circuits offer high performance and scalable manufacturing

Electro-optical devices that use wafers of lithium tantalate on an insulator have properties similar or superior to those of state-of-the-art lithium niobate-on-insulator wafers. They can also be made in larger volumes, at lower cost and using existing manufacturing infrastructure. Electro-optical devices based on lithium tantalate work as well as — or better than — current state-of-the-art materials and avoid some of their problems.
