Abstract
A new type of multimode fiber is provided, capable of being constructed without the need for chemical doping. The fiber contains a core region comprising a first material and one or more axially oriented elements disposed in the first material. The axially oriented elements (which typically extend throughout the length of the fiber) are configured to provide a graded effective refractive index profile or to provide more focused interaction with selected modes. The fiber further contains a cladding region surrounding the core region, where the cladding region exhibits a refractive index less than the effective refractive index of the portion of the core immediately adjacent the cladding region, i.e., there exists an index step at the core/cladding interface.
