Crealights’ Self-Developed Silicon Photonics Chip “Greyhound” Makes Its Appearance at CIIE, Showcasing a “Chinese Solution for the Token Economy”

November 11, 2026 -- From November 5 to 10, 2026, the 9th China International Import Expo (CIIE) was successfully held in Shanghai. “Greyhound”, a high-speed integrated silicon photonics transceiver chip independently developed by Crealights, made its appearance at the Beijing E-Town exhibition area. Under the theme “The Chinese Solution for the Token Economy,” the Beijing E-Town exhibition area focused on technological innovations across the energy, chip, infrastructure, model, and application layers. As an independently developed R&D achievement in the silicon photonics interconnect segment of AI computing architecture, “Greyhound” attracted attention from industry partners and professional visitors on site.

A Core Silicon Photonics Chip Designed for 3.2T/6.4T NPO

The name “Greyhound” symbolizes high speed, agility and low loss. It is a high-speed integrated silicon photonics transceiver chip independently developed by Crealights for high-bandwidth, low-power NPO optical interconnect scenarios. The chip is built on a 12-inch 65nm silicon photonics platform and paired with a 2.5D advanced packaging solution. It supports high-channel-density silicon photonics integration, shortens high-speed electrical interconnect distances between chips, reduces interconnect loss and system power consumption, and increases bandwidth density and packaging integration, providing a core silicon photonics solution for 3.2T/6.4T NPO optical interconnects.

In terms of technological extensibility, “Greyhound” is compatible with multiple NPO interconnect forms and can be extended to next-generation optical interconnect technology routes such as CPO and OIO, providing support for Crealights’ subsequent technology iteration and product layout.

Partnering with E-Town to Advance Collaborative Development of the Silicon Photonics Industry Chain

As an important carrier for Beijing’s high-end, high-precision and cutting-edge industries, E-Town is home to one of the most complete integrated circuit industry chains in China. Rooted in the E-Town industrial ecosystem, Crealights leverages its full-stack capabilities in silicon photonics chip design, wafer testing, packaging and coupling, and module manufacturing, while coordinating with the region's process platforms, packaging and testing capacity, equipment and materials support, and computing infrastructure layout, to promote efficient linkage across the design, manufacturing, packaging and application stages.

For technologies such as silicon photonics that require strong process-and-packaging collaboration, upstream-downstream coordination across the industry chain helps improve R&D validation efficiency and product iteration speed: by aligning design capabilities with process platforms and validating packaging solutions nearby, the cycle from tape-out to volume delivery is shortened, better matching the rapidly evolving interconnect demands of AI computing networks.

From domestic chips and domestic computing to domestic large models and the deployment of intelligent scenarios, E-Town continues to promote an integrated innovation chain. The appearance of “Greyhound” demonstrates the innovative achievements of silicon photonics technology in the field of AI computing interconnect and provides technical support at the optical interconnect level for “the Chinese Solution for the Token Economy.”
