➀ Researchers demonstrate active optical interposers for chiplet connectivity with minimal latency; ➁ CEA-Leti's Starac technology uses silicon photonics for improved performance and reduced latency; ➂ The technology aims to enable direct communication between chiplets, bypassing traditional routing methods.

➀ POET Technologies will collaborate with Mitsubishi Electric to develop integrated optical engine chipsets for 3.2T pluggable transceivers; ➁ Mitsubishi Electric will contribute its 400G Electro-absorption Modulator integrated Lasers (EMLs) to the project; ➂ POET will integrate the EMLs with drivers, optical waveguides, and other key functional building blocks to produce 1.6T and 3.2T optical engine chipsets.
