Presentation Abstract

Small, Bright, Efficient: Why Laser-LCoS is AR’s Next Leap

LCoS can deliver outstanding AR image quality—but illumination has often been the bottleneck: too bulky, too lossy, and too power-hungry for glasses-class designs. In this talk, we’ll show how a laser-based illumination architecture can remove that bottleneck and make Laser-LCoS a practical path to the next generation of AR displays.

Vitrealab’s Quantum Light Chip (QLC) integrates a three-dimensional waveguide network that routes RGB laser light and emits a controlled array of single-mode beams. The result is a compact, well-conditioned “light grid” optimized for LCoS modulation—maximizing optical efficiency while enabling high brightness in a simpler, smaller engine.

We’ll connect the photonics behind the approach to what matters most in AR glasses: longer battery life, larger field of view, and a clearer route to product-ready, scalable designs.
