Abstract
Multi-core optical fibers are disclosed herein. According to one embodiment, a multi-core optical fiber includes a common outer cladding formed from silica-based glass and having a cladding index of refraction n. At least one single mode core element may be disposed in the common outer cladding. The at least one single mode core element may have a maximum index of refraction n. In addition, at least one multimode core element may be disposed in the common outer cladding, the at least one multimode core element having a maximum index of refraction n. The maximum refractive index nof the at least one single mode core element may be greater than the cladding index of refraction n, the maximum refractive index nof the at least one multi-mode core element may be greater than n, and a center-to-center spacing between adjacent core elements is greater than or equal to 25 μm.
