A new, low-cost, high-efficiency photonic integrated circuit

Lithium tantalate photonic integrated circuits. Credit: Tobias Kippenberg (EPFL) The rapid advancement in photonic integrated circuits (PICs), which combine multiple optical devices and functionalities on a single chip, has revolutionized optical communications and computing systems. For decades, silicon-based PICs have dominated the field due to their cost-effectiveness and through their integration with existing semiconductor manufacturing […]
