Title: The Innovations of Yi Sun
Introduction
Yi Sun is a prominent inventor based in Suwanee, Georgia, known for his significant contributions to the field of optical fiber technology. He holds a total of 10 patents, showcasing his expertise and innovative spirit in developing advanced fiber designs.
Latest Patents
Among his latest patents, Yi Sun has developed multiple LP-mode fiber designs for mode-division multiplexing. One notable patent describes a few-mode fiber that features a graded-index core and a surrounding cladding with a ledge between the core and the trench. This design includes a down-doped trench adjacent to the ledge and an undoped cladding region next to the trench. The refractive index profile of the fiber is engineered to support nine or more LP modes for the transmission of spatially-multiplexed optical signals. The design effectively prevents coupling between desired and undesired modes by ensuring that the effective indices of the undesired modes are close to or less than the cladding index, resulting in leakage into the outer cladding.
Another patent focuses on nine LP-mode fiber designs for mode-division multiplexing, which also features a graded-index core and a similar cladding structure. This fiber is optimized for maximum differential group delay (MDGD) across a wide range of wavelengths, further enhancing its performance in optical communications.
