Abstract:
1. A holey fiber comprising: a core region that is formed at a center of the holey fiber; and a cladding region, formed at a circumference of the core region, and having a plurality of holes distributed as a triangle lattice around the core region, wherein the holey fiber has a fundamental mode zero-dispersion wavelength of less than 700 nm and a higher order mode at the fundamental mode zero-dispersion wavelength, and fundamental mode and higher order mode confinement losses are less than 0.1 dB/m and more than 10 dB/m, respectively, at the fundamental mode zero-dispersion wavelength, d/Λ is in a range of 0.7 to 0.97 and Λ is a range of 0.55 to 1.2 μm, where d is a diameter of the holes in μm and Λ is a lattice constant of a triangle lattice.
