January 2024 – Photonics Spectra has written an article which discusses the future of alternative, virtual, and mixed reality hinges on waveguide designs that can deliver user comfort, high functionality, and low cost.
With contributions from NIL Technologies, Lumus, Digilens,VividQ, Inprentus, and in particular, Andreas Georgiou, a Microsoft researcher and optical engineer with Reality Optics in Cambridge, the view is that extended and mixed reality is indeed in sight.
NIL Technology, which introduced its first diffractive gratings for AR in 2008, is seeing customers continuously request more advanced nanostructures to optimize their display performance.

This overlay image is expanded in the trapezoidal section for an expanded eye-box and finally projected out of the plane of the waveguide into the users’ eyes. Courtesy of NIL Technology.
