Los Angeles, U.S., March 16, 2026 – Siluxtek, a leading provider of advanced silicon photonic chips and solutions, successfully hosted its technical symposium themed Towards 400G per Lane during the 2026 Optical Fiber Communication Conference and Exposition (OFC) in Los Angeles, USA. The symposium brought together top experts and industry representatives from the global optical communications, silicon photonics, and AI interconnect sectors to address the surging demand for bandwidth and energy efficiency in data centers. Through thematic presentations and in-depth discussions, participants engaged in comprehensive exchanges on core technologies, engineering practices, and industrial ecosystems for the transition to 400G per lane intra-data center (intra-DC) links, unlocking new directions for the development of high-speed optical interconnects and building industry consensus for the practical application of this technology.
Currently, 400G per lane has evolved from an industry vision into a core technology imperative that the optical communications sector must address. Its advancement represents not merely a technical upgrade, but a fundamental transformation in optical communication design.
Centered on this key direction, the symposium conducted in-depth discussions on four core topics: the engineering challenges of 200 G baud modulators and their critical role in next-generation systems; the technical competition and selection considerations between DSP-intensive architectures and Low-Power Optics (LPO) architectures; key practical deployment points for 400G per lane technology in intra-data center links; and collaborative innovation and ecosystem construction in cutting-edge optical communications between GlobalFoundries, Siluxtek, and global industry partners. These explorations provided multi-dimensional insights and references for technology implementation and industrial development.
The symposium offered attendees a knowledge feast featuring both profound technical depth and industry foresight:
1. Invited Dr. Kevin Dezfulian from GlobalFoundries shared their core capabilities and practical experience in semiconductor manufacturing that support the deployment of 400G per lane technology, providing guidance for technological breakthroughs in underlying hardware manufacturing.
2. Dr. Patrick Lo from Advanced Micro Foundry focused on advanced processes and photonic chip integration, and delivered an in-depth discussion on the critical role of process upgrades in improving the performance of optical communication chips.
3. Dr. Chongjin Xie, Founder and CEO of PhotonicX AI (Prior to launching the company in 2024, he was a senior director and chief communication scientist at Alibaba Cloud), delivered a speech themed Scaling Optics for AI Interconnects. Combining the unique requirements of AI interconnect scenarios, he analyzed the upgrade pathways and large scale application strategies for optical module technologies.
4. Dr. Christopher Doerr, Founder and CEO of Aloe Semiconductor (previously led the silicon photonics team at Acacia Communications), provided an in-depth interpretation of silicon photonic technologies enabling 1.6T IMDD and higher speeds over a single fiber pair, exploring the future possibilities of optical communication rate upgrades from a cutting-edge technical perspective.
5. Dr. Fuwan Gan, Founder and CEO of Siluxtek, delivered a keynote on key technologies for 400G per lane silicon photonic modulators in AI computing centers. He shared Siluxtek’s core R&D achievements, engineering practices and technological breakthroughs in this field, demonstrating the strong capabilities of domestic silicon photonics enterprises in cutting-edge technologies.
The successful symposium established an open industry dialogue platform for advancing 400G per lane intra-data center link technologies. It facilitated technical exchanges and experience sharing across the global optical communication industry chain, and strengthened consensus on collaborative innovation within the industrial ecosystem.
