  • SURFACE RELIEF GRATING AND METHOD OF MAKING THE SAME
    Publication number: 20230057283
    Abstract: There is provided a method that includes depositing a plurality of layers in a substrate including a pattern. The plurality of layers can form a stack that includes at least two different materials. The stack thus forms a composite layer which has an effective index of refraction that is unique.
