Aylight Raises €4.5M for Optical Chip Technology

Zurich-based deeptech innovator, Aylight, has successfully closed a significant €4.5 million pre-seed funding round. This capital infusion is earmarked to accelerate the development of its groundbreaking chip-scale multiwavelength laser technology, poised to revolutionize optical interconnects within burgeoning AI data centers and high-precision sensing applications. The round saw robust participation from prominent investors, co-led by Elaia and Swisscom Ventures, with additional backing from Verve Ventures and Plug and Play.

Founded by seasoned researchers Bahareh Marzban and Dmitry Kazakov, who emerged from the esteemed ETH Zürich ecosystem, Aylight is addressing a critical bottleneck in the exponential growth of artificial intelligence infrastructure. Their core innovation lies in a novel frequency-modulated comb (FM comb) architecture, enabling a single chip to generate multiple, precisely spaced wavelengths. This contrasts sharply with traditional approaches that necessitate numerous discrete lasers, thereby promising substantial gains in efficiency and miniaturization for optical communication systems.

The escalating demand for enhanced data transfer speeds and reduced latency within AI data centers underscores the market's readiness for Aylight's solution. As AI models become more complex and data volumes surge, the physical limitations of chip-to-chip communication are becoming increasingly apparent. Aylight's technology directly confronts this challenge by offering a more integrated and powerful optical solution, designed for seamless integration with existing semiconductor photonics foundry processes.

Beyond its primary focus on AI data center interconnects, Aylight's versatile laser technology holds considerable promise for a range of other demanding sectors. Applications in semiconductor inspection, advanced metrology, industrial automation, and precision robotics, all of which rely heavily on high-resolution three-dimensional sensing capabilities, stand to benefit significantly from this innovation. The ability to generate multiple wavelengths from a single, compact chip opens up new frontiers for sensing accuracy and system design.

Bahareh Marzban, co-founder and CEO of Aylight, articulated the company's mission, stating, "We identified a fundamental constraint hindering the scalability of AI infrastructure – the laser itself. This funding is instrumental in propelling our technology from its research origins to market-ready products." The newly acquired capital will be strategically deployed to develop the company's initial semiconductor-foundry prototypes and to significantly expand its dedicated research and development team, solidifying its position at the forefront of photonic innovation.

The market for optical interconnects is projected for substantial growth, driven by the insatiable appetite for data processing power. Industry analysts forecast the global optical interconnect market to reach tens of billions of dollars in the coming years, with AI and high-performance computing being key growth engines. Aylight's pre-seed funding positions it to capture a significant share of this expanding market by offering a demonstrably superior technological solution.
