LARGE MODE-AREA MICROSTRUCTURED OPTICAL FIBER

摘要

A large mode-area microstructured optical fiber includes a core, at least one axially oriented element disposed in the core, and a cladding about the core. The axially oriented element has a refractive index less than a refractive index of the core. The axially oriented element(s) defines sectional regions in the core. The sectional regions defined by the axially oriented element(s) can discriminate between symmetric and antisymmeteric modes of an optical beam that propagates through the optical fiber.
