HyperLight Corporation

HyperLight is a Cambridge, Massachusetts company that designs and manufactures photonic integrated circuits on thin-film lithium niobate (TFLN), a material prized for ultrafast, low-voltage electro-optic modulation. A 2018 spin-out from Marko Loncar's lab at Harvard, the company built what it describes as the industry's first high-volume, qualified 6-inch TFLN manufacturing line - now expanding to 8-inch - and packages it as a modular TFLN Chiplet platform. Its modulator chips target the bandwidth and power-efficiency demands of AI data centers, telecom optical networks and high-performance computing, enabling 1.6 Tbps-class links at CMOS-level drive voltages.
