Shanghai, March 16, 2026 — The global optical communication industry has achieved a milestone breakthrough! Silux Technologies Co., Ltd. (Siluxtek) announced today the formation of a deep strategic partnership with GlobalFoundries (GF), the world’s largest pure-play silicon photonics foundry. Leveraging GlobalFoundries' advanced silicon photonics process technology, the two parties will focus on advancing the large-scale mass production of 200G/Lane high-speed silicon photonic receiver (Rx) chips, and simultaneously provide a comprehensive turnkey solution for 100G/200G per lane silicon photonic transmitter (Tx) chips. This initiative will build a robust hardware foundation of core devices for next-generation AI computing clusters, hyperscale data centers, and high-density interconnect scenarios.
The landmark achievements of this strategic cooperation will be officially unveiled at OFC 2026 (Optical Fiber Conference), with the highlight on the 200G/Lane high-speed silicon photonic receiver chip. Siluxtek will set up a booth at No. 4770 in the West Hall of the Los Angeles Convention Center from March 17 to 19, inviting industry partners worldwide to visit and exchange ideas, and explore cutting-edge optical communication technologies and new opportunities for industrial collaboration.
Breaking the Bottleneck of Computing Interconnects: 200G/Lane Receiver Chips as the Critical Pivot
As the parameters of AI large language models grow exponentially, AI chip clusters are imposing extreme requirements on interconnect bandwidth, power consumption control, and integration density. Single-channel 200G technology has become the core solution for 800G/1.6T optical transceivers and Co-Packaged Optics (CPO) systems. As the "core gateway" of signal links, the sensitivity, transmission bandwidth, and power performance of high-speed receiver chips directly define the performance upper limit of the entire optical transmission system.
The 200G/Lane silicon photonic receiver chip at the heart of this collaboration adopts advanced PAM4 modulation technology and a silicon photonic integrated architecture, boasting core advantages such as ultra-low power consumption, ultra-compact size, and high reliability. It is perfectly tailored to the deployment needs of high-density data centers and next-generation AI computing infrastructure. In tandem with Siluxtek's mature 100G/200G per lane silicon photonic transmitter chips, the chip delivers a full-link integrated silicon photonic transceiver solution for customers, providing one-stop technical support from design to application.
Deep Integration Across the Entire Value Chain: Closing the Loop from High-End Design to Large-Scale Mass Production
At present, the 200G/Lane silicon photonic receiver chip co-developed by the two parties has successfully completed tape-out and validation. It is scheduled to officially sample to the market in the second quarter of 2026 and achieve large-scale mass production in the third quarter. Endowed with leading technical performance and adaptability, the product has already secured intentions for bulk orders from top China domestic and international optical transceiver manufacturers, cloud service providers, and computing infrastructure suppliers. Meanwhile, Siluxtek's 100G/Lane and 200G/Lane silicon photonic transmitter chips have entered the mass production phase, and customized supporting solutions for customers will be advanced in parallel to realize the commercialization of transceiver chips.
This strategic cooperation integrates the core strengths of both parties:
• Siluxtek: Leverages its full-stack technical capabilities in high-speed silicon photonic chip design, packaging and testing and system solutions. It takes the lead in the architectural design, performance optimization, and customized services of both receiver and transmitter chips, meeting the transmission needs across all data center scenarios.
• GlobalFoundries: Provides an industry-leading silicon photonics process technology, silicon-proven manufacturing capabilities, and large-scale mass production guarantees, ensuring the high yield and supply chain stability of receiver chips from the perspective of production processes.
Industry Insights: Jointly Building a High-Speed Optical Interconnect Ecosystem
Gan Fuwan, Founder and CEO of Siluxtek, stated: "The AI computing revolution is placing unprecedented and extreme demands on the speed, power consumption, and integration of optical interconnects, and the 200G/Lane receiver chip is a core demand for the next-generation optical communication industry. Having deeply rooted itself in the industrialization of silicon photonic chips for many years, Siluxtek has successfully opened up the entire industrial chain from high-end design to large-scale mass production through this strategic cooperation with GlobalFoundries, and will deliver industry-leading silicon photonic receiver solutions to global customers. OFC is the global bellwether for optical communication technology innovation, and we are delighted to announce this cooperation achievement at this year's conference. We will accelerate the upgrade of AI computing infrastructure with our most competitive 200G per lane receiver technology."
Thomas Barber, Vice President of Communications Infrastructure and Data Center End Markets at GlobalFoundries, commented: "GlobalFoundries continues to expand our ecosystem and develop new innovations in silicon photonics technology to empower our customers to build leading, high-speed optical interconnect chip products. Siluxtek's technological innovation and market implementation capabilities in the silicon photonics field are well-regarded across the industry. By joining hands to advance the mass production of 200G/Lane receiver chips, we will further improve the high-speed optical interconnect ecosystem in the fields of data centers and AI computing, provide stable and high-performance core device support for the global optical communication industry, and drive the industry towards higher speeds and greater integration."
