Speckle-free Photonics Integrated Circuit based Light Engine Using Superluminescent Diodes for Next-generation Augmented Reality Glasses

Cel

Virtual world technologies, such as augmented reality (AR), will only achieve wide adoption if they deliver user comfort, immersive experiences, and affordability. Current AR glass demonstrators, based on micro-LEDs or conventional liquid-crystal-on-Si (LCoS), suffer from bulky form factors, high energy consumption, limited display performance, and high manufacturing cost. These barriers significantly hinder acceptance and everyday use.
The SLDAR project will overcome these challenges by developing the next generation of compact, speckle-free, and energy-efficient light engines for AR glasses. Its core ambition is to combine superb display performance with a volume below 1 cm³, enabling lightweight designs suitable for all-day wear and seamless user experience.
SLDAR will deliver three major breakthroughs:
1. Advanced visible light sources with speckle-free, high-brightness emission, based on superluminescent diodes (SLDs).
2. An ultralow-loss aluminium oxide photonic integrated circuit platform, integrated with SLDs through micro-transfer printing, targeting a six-fold efficiency improvement over state-of-the-art LCoS engines.
3. System integration of PIC-based illuminators with custom optics and ferroelectric-LCoS displays into multi-generation AR glass prototypes, achieving unprecedented resolution and wide field-of-view, validated through user perception and societal adoption studies.
The consortium brings together leading European expertise across the full value chain—from photonic devices and PIC platforms to AR optics, microdisplays, end-user validation, and social sciences. By directly addressing Area B of the Core Technologies for Virtual Worlds call, SLDAR will deliver scalable AR technologies that combine performance, comfort, and affordability. In doing so, the project will reinforce Europe’s technological sovereignty and industrial leadership in the competitive AR domain, supporting a sustainable and user-centred digital future.
