  • Large mode-area microstructure optical fiber
    Publication number: 20060204190
    Abstract: 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.
