Micron Technology had four patents in connectivity during Q2 2024. Micron Technology Inc has developed a coupling structure for efficiently transferring optical signals between an integrated circuit photonic structure and an external optical fiber. The sloped design ensures that light entering or leaving the photonic structure is perpendicular to its upper surface, improving signal transmission.

Application: Photonics grating coupler and method of manufacture (Patent ID: US20240134122A1)
The patent filed by Micron Technology Inc. describes a structure for coupling an optical signal between an integrated circuit photonic structure and an external optical fiber. The coupling structure is sloped relative to the photonic structure's horizontal surface to ensure that light entering or leaving the structure is normal to its upper surface. The integrated photonic structure includes a substrate, lower cladding material, waveguide core, and upper cladding material with a sloped grating coupler for redirecting light.
The sloped grating coupler in the integrated photonic structure comprises spaced grooves in the upper cladding material and a sloped portion of the waveguide core. The grooves are oriented vertically relative to the planar upper surface of the structure and have specific dimensions and periods. Additionally, the structure may include an oxide material, a collar for the optical fiber, and the waveguide core can be made of various materials like silicon, silicon nitride, or gallium arsenide. The method of making the integrated photonic structure involves sequentially disposing the substrate, lower cladding material, waveguide core, and upper cladding material with the sloped grating coupler. Additional steps include adding an oxide material, grooves, and a collar for the optical fiber.
