Optical fibers are fundamental components due to their underlying benefits in modern science and technology, providing an efficient and safe medium for applications such as Internet communication and Big data transmission. Compared to single-mode fibers (SMFS), multimod fiber (MMFS) can support a large number of guided mode (~ 103 to ~ 104), which is high-capacity information and image transportation within a hair diameter Offer attractive benefits. , This capacity has deployed MMFS as an important tool in areas such as quantum information and micro-endoscopy.
