What Enlightra does

Enlightra is a Swiss-American deeptech startup, founded in 2021 and headquartered in Lausanne, Switzerland, that develops chip-scale multiwavelength laser technology for optical interconnects. The company was spun out of EPFL (École Polytechnique Fédérale de Lausanne) and emerged from stealth in December 2025 with $15 million in seed and Series A funding. Its core product, the Comb Laser Engine, is a silicon-photonics-based device that emits dozens of high-power laser wavelengths from a single chip, enabling terabit-class optical links that replace copper interconnects between GPUs and other data center components. The company has also demonstrated a proof-of-concept Photonic AI Inference Engine combining its laser source with phase-change-memory cells, achieving two trillion operations per second at 17mW with over 100 TOPS per watt efficiency, though this is an exploratory extension rather than a commercial product today.

Enlightra's target customers are operators of AI data centers and high-performance computing infrastructure that face bandwidth and power constraints from copper wiring as AI training and inference workloads scale. The company's go-to-market is enterprise-direct B2B sales of hardware components, with pilot production targeted for 2027. Revenue mechanics are expected to center on Comb Laser Generator sales, with the photonic AI inference product, if commercially pursued, dependent on the same generator platform. Enlightra has assembled an extensive institutional partnership stack including the NVIDIA Inception Program (accepted March 2026), Intel, DARPA, ESA, Fraunhofer, DESY, the European Commission, and Swiss innovation programs (Innosuisse), alongside financial backers such as Y Combinator, Runa Capital, Protocol Labs, and Pegasus Tech Ventures.

The company is led by co-founder and co-CEO John Jost and founder and CEO Maxim Karpov, and operates with 11–50 employees. Its near-term execution milestones are engineering-driven: maturing the Comb Laser Engine to pilot production by 2027, converting ecosystem relationships into design wins, and demonstrating commercial-grade reliability for hyperscale AI customers. Beyond AI data centers, potential application domains identified by the company include quantum communications, subsea optical links, chip-to-memory interconnects, and space-based optical communication systems.
