This abstract first appeared for US patent application 18894603 titled 'OPTICAL DEVICES AND METHOD OF MANUFACTURING OPTICAL DEVICES

Original Abstract Submitted

An optical device includes a metasurface formed by a metasurface substrate having at least a first metasurface layer made of a first material and an array of pillars extending through the first metasurface layer. The pillars are made of a second material different from the first material. The metasurface has a first face and a second face opposite the first face. A first anti-reflection stack is positioned over the first face of the metasurface. The first anti-reflection stack has a third face and a fourth face opposite the third face and positioned over the first face of the metasurface. A metal trace has a portion which is exposed at the third face of the first anti-reflection stack.
