SANTA BARBARA, Calif.--(BUSINESS WIRE)--Lucidean, a Santa Barbara–based AI interconnect company pioneering coherent optical links for data centers, announced that Dr. James Raring has joined as Chief Executive Officer and that the company has raised $18 million in Seed financing. The Seed funding was co-led by Entrada Ventures and Koch Disruptive Technologies (KDT), with participation from Foothill Ventures, M Ventures, Cerberus Ventures, and Raptor Group. With this Seed funding and strong syndicate, Lucidean will expand R&D efforts, validate the performance and efficiency of the CohZero™ platform, and accelerate productization.
“Lucidean is addressing a critical gap in the optical-interconnect market where existing intensity-modulation direct-detection (IMDD) and coherent solutions will both fall short,” said Dr. Alexander Fang, Managing Partner at Entrada Ventures. “With CohZero™, the company delivers coherent-class performance within the simplicity and power envelope of IMDD, backed by a uniquely capable technical and leadership team poised to tackle AI-scale networking.”
Data centers today face a tradeoff: simple, low-cost IMDD optical links that work only over short distances, or high-performance coherent links that require expensive, power-hungry equipment. Lucidean’s CohZero™ architecture eliminates this tradeoff by introducing a new class of coherent optical interconnects designed for seamless adoption in today’s data-center and AI/ML networks. CohZero™ is designed to operate entirely within the existing IMDD ecosystem including IMDD-class lasers already in widespread use, simplified DSPs including compatibility with IMDD DSPs, standard pluggable module architectures, and within both retimed and non-retimed applications including co-packaged optics while delivering coherent-class link budget, reduced impact from fiber impairments, and expanded data rates. This unique combination enables hyperscalers to scale to multi-terabit coherent performance without tight wavelength control, the overhead of traditional coherent DSPs, or disruptive physical-layer redesigns.
“AI networks are outgrowing legacy optical approaches,” said Dr. James Raring, CEO of Lucidean. “CohZero™ delivers coherent-class optical links with zero overhead. Our recent seed funding and strong syndicate of investors perfectly positions Lucidean for our next phase of growth where we will accelerate hiring and expand our capabilities to rapidly demonstrate our value proposition in hardware and move towards productization.”
Dr. Raring, who has been deeply engaged with Lucidean’s leadership team throughout the company’s recent evolution, is a veteran photonics entrepreneur and technologist with more than two decades of leadership in laser and optical-communications innovation. He joins Lucidean co-founders and Co-CTOs Dr. Hector Andrade and Dr. Aaron Maharry along with academic co-founders Dr. Clint Schow and Dr. Larry Coldren. Before his work with Lucidean, Dr. Raring co-founded and served as CEO of Kyocera SLD Laser, where he led the development, commercialization, and global shipment of high-brightness GaN laser-light sources in the automotive and specialty-lighting sectors. Earlier in his career, he developed the first single-chip 40 Gb/s all-optical transceiver. Dr. Raring holds more than 300 patents and brings a proven record of scaling deep-tech innovation from lab to production.
“KDT is excited to co-lead Lucidean’s latest funding round as the company scales a breakthrough technology for next-generation AI and cloud networks,” said Isaac Sigron, Managing Director at KDT Israel, an affiliate of KDT. “CohZero™ delivers coherent-class reach and bandwidth within IMDD-like cost and power envelopes, offering a clear path to ultra-high-capacity interconnects at AI scale. Lucidean is exceptionally well-positioned to redefine optical performance for modern data centers.”
