Abstract
Official abstract text for this publication.
Embodiments of auto-cladded optical fibers are described. The fibers may have a refractive index profile having a small relative refractive index change. For example, the fiber may include an auto-cladded structure having, e.g., a trough or gradient in the refractive index profile. A beam of light propagating in the fiber may be guided, at least in part, with the auto-cladded structure. In some embodiments, the optical fiber may be all glass. In some embodiments, the optical fiber may include a large-core or an ultra large-core.
First claim
Opening claim text (preview).
What is claimed is: 1. An all-glass fiber comprising: a core and cladding material, said core and cladding material comprising an interface, said core and cladding material selected from substantially identical glasses, said fiber configured to support low-loss propagation of at least the lowest-order core mode, wherein said fiber comprises at least one of an index trough at the core-cladding interface or an index gradient within said core, and wherein a mode diameter of sai…
