Copper damascene process brings electronics and photonics together

Published:02.03.26 — EPFL researchers have, for the first time, applied the semiconductor industry’s standard copper wiring process to ferroelectric thin film photonics. By building lithium tantalate modulators with copper instead of gold, they remove a major barrier to 3D integration with advanced CMOS electronics and move optical interconnects closer to large scale deployment in data centers and AI clusters.
