A single-polarization optical fiber of hollow pit type with zero total dispersion at wavelength of 1.55 μm

Optical waveguide design using inverse transmission line techniques

“…A fiber in which the dispersion is low over a broad wavelength range is defined as the dispersion flattened fiber. A few refractive index profiles for an optical fiber have been proposed to get dispersion zero or flattened characteristics over a wavelength range of 1300 nm to 1550 nm (Frenkel, Heritage et al 1989;Hinata, Furukawa et al 1994;Lundin 1994;Survaiya and Shevgaonkar 1996). Dispersion can also be controlled using dispersion management (Ennser, Ibsen et al 1998).…”
