This abstract first appeared for US patent application 20250110263 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.
