TeraHop
TeraHop is an optical solutions provider building high-speed optical transceivers and modules for AI clusters and data centers. Operating from Singapore, San Jose, Thailand and a new Texas plant, it ships 400G, 800G, 1.6T and emerging 12.8T-class optics. As the international-facing arm of Zhongji InnoLight - the world's largest optical-transceiver maker - TeraHop pairs high-volume manufacturing with R&D partnerships across NVIDIA, Marvell and Corning, and in 2025-2026 raised roughly US$517M with backing from Abu Dhabi's ADIA and Singapore's Temasek.
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.
