HyperLight Raises $80M in Series C Funding Led by MediaTek

The round also saw participation from UMC Capital, Jabil, Foxconn, EDBI, CDIB-TEN Capital, Qatar Investment Authority (QIA), Summit Partners, The Engine, Foothill Ventures, and Xora Innovation.

The company plans to use the funds to increase manufacturing capacity, speed up customer qualification processes, expand its TFLN Chiplet Platform, and strengthen partnerships across the foundry, semiconductor, networking, and systems integration industries.

HyperLight’s TFLN Chiplet™ Platform is designed to support a wide range of optical networking applications, including short-range data center connections, long-range datacom and telecom networks, and co-packaged optics (CPO), all within a single scalable architecture.

The platform currently supports 200G-per-lane operation, while 400G-per-lane products are already being tested by customers. It combines high bandwidth, low drive voltage, and low optical loss to improve performance while reducing power consumption.

As AI infrastructure grows and requires faster optical connectivity, HyperLight aims to support future networks operating at 3.2T and beyond. According to Brian Hsu, Managing Director of MediaTek Innovation Fund, TFLN technology offers the bandwidth and efficiency needed for next-generation high-speed interconnects, positioning HyperLight well for future demand.

HyperLight’s platform combines a wide range of customer needs into a single standardized and production-ready architecture. This simplifies the ecosystem, reduces manufacturing risks, and helps customers adopt TFLN photonics more quickly and cost-effectively at scale.

“This financing is about more than capital — it is about ecosystem alignment,” said Mian Zhang, CEO of HyperLight. “AI infrastructure requires optical interconnects that can deliver higher bandwidth, lower power, and manufacturing scale across pluggable optics and co-packaged optics. HyperLight has spent years building the TFLN technology, manufacturing foundation, and ecosystem relationships required to support that transition. This round accelerates our ability to scale with customers and partners globally.”
