Rob Guzzon of OpenLight presents the 1.6T DR8 PIC and evaluation board

Rob’s demonstration showcases a high-speed optical link representative of rack-to-rack data center connectivity in AI clusters. It features flip-chip co-packaging with OpenLight’s 1.6T silicon photonics DR8 PIC, comprising eight 200G lanes and including heterogeneously integrated, 1310 nm DFB lasers, InP-based 224G EAMs, amplifiers, and photo detectors. The Marvell Ara 3 nm 1.6T DSP conditions and processes electrical signals before they are converted to light.

The PIC is designed for use in optical modules or CPO systems to deliver high‑bandwidth optical links, supporting 1.6T today but enabling 3.2T in future.
