Abstract
A holey fiber has at least: a core portion positioned at a center of the holey fiber; a cladding portion positioned around the core portion and including holes that are formed in layers around the core portion and that form a triangular lattice; d/Λ in a range of 0.43±0.03; Λ of 20 to 24 micrometers; a single-mode operation demonstrated at a wavelength of 1550 nanometers; and an effective core area equal to or larger than 500 μm2 at the wavelength of 1550 nanometers, wherein d is a diameter of each hole in micrometers, and Λ is a lattice constant of the triangular lattice in micrometers.
