Double-core optical fiber is a kind of special optical fiber with special refractive index distribution. It breaks through the refractive index distribution structure of conventional optical fiber, and two parallel cores are arranged in the same optical fiber. It can be used as an optical transmission medium and new optical devices can be constructed. In a conventional dual-core fiber, the two cores are close together, and when light propagates through one of the cores, the other core can be regarded as a perturbation structure, which results in optical power coupling between the two cores.
