Design of a flat field fiber with very small dispersion slope

We have given designs of a small dispersion fiber with large effective area and small dispersion slope. The fiber has flat modal field over the central part of the core, which provides large mode field diameter (8.3 um at Λ0 = 1550 nm) leading to the relatively large effective area (Aeff = 56.1 um ) required to reduce nonlinear effects. The total dispersion… CONTINUE READING
