Minimization of the chromatic dispersion over a broad wavelength range in a single-mode optical fiber
Författare
Summary, in English
The effective refractive-index as a function of vacuum wavelength is approximated
by Lagrange interpolation polynomials. The root-mean-square value
of the chromatic dispersion is then calculated analytically. It is demonstrated
that use of fourth degree polynomials is far more efficient than use of second
degree polynomials. The rms-value of the chromatic dispersion over the wavelength
range [1.25 µm, 1.60 µm] is calculated and minimized for step-index
fibers, triangular-index fibers, and α-power fibers. The full vector solution of
Maxwell’s equations is used. It is demonstrated that the approximate model
of the refractive-index, used in this paper and in other papers, induces an error
in the rms-value which is not negligible when designing dispersion-flattened
fibers.
