GlobalFoundries Thomas Barber: CPO, Silicon Photonics, 300mm, SiGe, OCI, NRZ
GlobalFoundries’ Thomas Barber argues that silicon photonics is becoming the practical answer to copper’s shrinking reach in AI data centers, especially for scale-up networks inside and across racks. He explains how GF combines 300mm silicon photonics, specialty silicon germanium, and the OCI optics ecosystem to push lower-power, higher-density interconnects.
