VitreaLab
Photonic Quantum Light Chip for laser AR light engines
About VitreaLab
VitreaLab is a Vienna deeptech company founded in 2018 by Dr Chiara Greganti and Dr Jonas Zeuner as a spin-off from the University of Vienna Quantum Group. It develops photonic integrated circuits for laser–LCoS AR light engines, including its proprietary Quantum Light Chip that guides and shapes laser light through laser-written glass waveguides for compact, high-brightness, energy-efficient AR displays. The company fabricates devices in-house with proprietary direct laser writing and works with Tier-1 OEMs toward mass-market AR glasses. After earlier seed financing (including a PhotonVentures-led round), VitreaLab closed a €9.4 million ($11 million) Series A in January 2026 led by LIFTT Italian Venture Capital and LIFTT EuroInvest, with Constructor Capital, aws Gründungsfonds, Gateway Ventures, PhotonVentures, xista Science Ventures, Moveon Technologies and Hermann Hauser Investment, to industrialise the Quantum Light Chip and advance next-generation light-engine architectures.
