Application: Photonic integrated circuit structure with at least one tapered sidewall liner adjacent to a waveguide core (Patent ID: US20240210621A1)
The patent filed by Global Foundries Inc. discloses embodiments of a photonic integrated circuit (PIC) structure with a waveguide core having tapered sidewall liners. These liners can be symmetric or asymmetric and have different refractive indices compared to the waveguide core. The structure includes protective layers, insulator layers, and dielectric layers positioned in specific configurations to enhance the performance of the PIC structure.
The claims associated with the patent detail various configurations of the structure, including different heights of the tapered sidewall liners compared to the waveguide core, the presence of protective layers and dielectric layers, and the use of specific materials with varying refractive indices. The claims also cover structures with asymmetric tapered sidewall liners, dielectric layers extending over the liners, and protective layers on the waveguide core. These configurations aim to optimize the functionality and efficiency of the PIC structure for applications in integrated photonics.
