HyperLight introduced a new family of 400G-per-lane photonic integrated circuits based on thin-film lithium niobate, targeting the next wave of AI networking infrastructure. The Cambridge, Massachusetts company said the new PICs deliver low insertion loss, low drive voltage operation, and high electro-optic bandwidth to support higher-speed optical links as AI interconnect requirements move beyond current lane speeds.
The announcement puts HyperLight directly into the emerging 400G-per-lane optical ecosystem now taking shape around 1.6T modules and future 3.2T designs. HyperLight said its TFLN devices combine high modulation efficiency with very low optical loss, enabling transmitter architectures based on single- or dual-laser designs and potentially lowering module power. Broadcom also tied the PICs to its Taurus optical DSP platform, which Broadcom introduced on March 11, 2026 as a 3nm 400G-per-lane PAM4 DSP for 1.6T transceivers and a building block for future 204.8T switching systems.
The product launch follows a series of manufacturing and ecosystem moves by HyperLight this month. On March 11, HyperLight, UMC, and Wavetek announced a strategic manufacturing partnership for high-volume foundry production of the TFLN Chiplet Platform on both 6-inch and 8-inch wafers, and HyperLight also highlighted a collaboration with Jabil aimed at accelerating deployment of TFLN photonics into hyperscale AI data center interconnects. Together, those steps suggest HyperLight is trying to position TFLN not as a specialty photonics technology, but as a manufacturable platform for AI-scale optical interconnects.

“400G-per-lane is a prime example of where the advantages of TFLN become clear,” said Mian Zhang, CEO of HyperLight. “While 400G-per-lane pushes the limits of many technologies from a bandwidth perspective, TFLN provides ample bandwidth margin while maintaining low drive voltage. This enables excellent manufacturability while significantly reducing module power.”
