Vienna’s Vitrealab Raises €9.4M For Laser-Based AR Display Technology

The funding will accelerate development of its Quantum Light Chip (QLC) for AR displays.

The round was significantly oversubscribed and led by LIFTT Italian Venture Capital and LIFTT EuroInvest, with participation from Constructor Capital, aws Gründungsfonds, Gateway Ventures, PhotonVentures, xista Science Ventures, Moveon Technologies, and Hermann Hauser Investment.

“The successful closing of our Series A is a strong validation of our technology and our vision for scalable AR display systems. This funding allows us to move from advanced prototypes to industrial-grade solutions while continuing to push the boundaries of what is possible with photonic integrated circuits in display applications ” said Dr Jonas Zeuner, CTO and co-founder of Vitrealab.

Founded in 2018 by Chiara Greganti and Dr. Zeuner, Vitrealab is a deeptech company on a mission to transform the display industry through innovative laser waveguide technology. The company is a spin-off from the Quantum Group at the University of Vienna, with Nobel Laureate Anton Zeilinger among its founding members.

Vitrealab develops photonic integrated circuits (PICs) for laser–liquid-crystal-on-silicon (LCoS) AR light engines. Its proprietary Quantum Light Chip (QLC) enables compact, high-brightness and energy-efficient light engines tackling key performance and scalability challenges for next-generation AR glasses.

The company follows a vertically integrated approach enabling seamless scaling from prototype to volume production. This is supported by its in-house manufacturing capabilities and proprietary direct laser writing technologies, which allow Vitrealab to design and fabricate its own photonic devices.

At the core of its technology, photonic integrated circuits guide and shape coherent laser light for LCoS light engines. According to the company, this method reduces system complexity, optical losses and overall size, while preserving polarization and beam quality. The result is higher brightness, wider fields of view, and lower power consumption, all in a form factor suitable for lightweight AR smart glasses.

The latest funding will accelerate the development and industrialisation of the QLC, strengthen collaborations with customers and partners, demonstrate next-generation light engine architectures, and further advance the technical capabilities required for widespread AR adoption.

Previously, in 2021, Vitrealab completed a seven-digit Seed round led by APEX Ventures to scale its display solutions. The company collaborates with leading Tier-1 OEMs and technology partners to bring high-performance AR glasses to the mass market.
