Dispersion flattening in a w-fiber

Lundin, Richard LU (1993) In Technical Report LUTEDX/(TEAT-7024)/1-7/(1993) TEAT-7024.
Abstract
A method for dispersion-flattening in double-clad single-mode optical fibers

is presented. The chromatic dispersion over the wavelength range [1.25 µm,

1.60 µm] is minimized for a w-fiber and also for a triangular-index fiber with

a depressed inner cladding. The constraint that the first higher order mode

should appear exactly at 1.25 µm is imposed. The full vector solution of

Maxwell’s equations is used. Applying an approximate refractive-index model,

it is found that the w-fiber is capable of yielding a rms-dispersion less than

1 ps/(km nm). A doping level of two per cent in the core is necessary to

achieve this. How to interpret this numerical result is not... (More)
