Talk Title: Broad Ion Beam Processing for Scalable Manufacturing of Blazed Gratings for AR Waveguides
Date: Wednesday, 16 September, 5:20 pm
Location: Track 2 - Room Ernst & Curie (1st Floor)
As Augmented Reality devices move toward mass adoption, waveguide optics require higher efficiency, improved image quality, and scalable manufacturing processes. This presentation explores a Broad Ion Beam processing approach for fabricating and finishing blazed surface relief gratings on 200 mm wafers. The technique delivers excellent blaze angle and etch depth uniformity while significantly reducing surface roughness. The results demonstrate a practical, wafer scale manufacturing route for high-performance AR waveguides, supporting both R&D and high-volume production of next-generation AR optics.
