Abstract

Blazed gratings are widely used for surface relief grating (SRG) waveguides for augmented reality displays. To increase the efficiency and design freedom of blazed gratings the control of the anti-blaze angle has gained attention lately. We will demonstrate mastering processes to realize blazed gratings with positive, vertical and negative anti-blaze angles on masters for the replication of SRG waveguides.
