Application: Optical components with an adjacent metamaterial structure (Patent ID: US20240168199A1)
The patent filed by Global Foundries Inc. describes structures for an optical component, specifically a polarization splitter rotator, and methods for forming such structures. The structure includes a waveguide core positioned vertically over a substrate, with a metamaterial structure positioned laterally adjacent to the waveguide core. This metamaterial structure consists of elements separated by gaps filled with a dielectric material.
The patent claims detail the specific configurations and materials used in the structure, such as multiple waveguide cores, metamaterial structures with different elements and dielectric materials, and the positioning of light sources in relation to the waveguide cores. The method outlined involves forming the waveguide core vertically over a substrate and then creating the metamaterial structure laterally adjacent to the waveguide core, with specific elements and dielectric materials used in the process. Overall, the patent focuses on the design and fabrication of optical components with precise configurations to achieve desired functionalities.
