Application: Compact dual polarization couplers for multi-core optical fibers (Patent ID: US20240126014A1)
The patent filed by Corning Inc. describes a fiber coupler for integrating multi-core optical fibers with photonic devices. The fiber coupler includes a grating array with polarization splitting gratings corresponding to the cores of the optical fiber. Mode converters are used to receive and guide different polarization modes of the optical signal, ensuring efficient coupling into waveguides. The design allows for the coupling of multiple polarization modes, with specific requirements for core-to-core separation distances and core diameters to optimize performance.
The claims detail various aspects of the optical device, including core separation distances, core diameters, and the number of cores in the multi-core optical fiber. The design of the fiber coupler, including the dimensions of the polarization splitting gratings and mode converters, is specified to ensure efficient coupling of different polarization modes. Additionally, the method described in the patent outlines the process of transmitting optical signals from the multi-core optical fiber to the photonic integrated circuit using the grating array and mode converters. Overall, the patent focuses on the efficient coupling of multiple polarization modes in multi-core optical fibers to enable seamless integration with photonic devices.
