Dispersion in optical fibers: new aspects.
Group delay differences among modes, which limit the bandwidth of optical fibers, arise not only from distortions of the refractive profile but also from profile dispersion caused by the dependence of the profile contour on wavelength. An efficient method is presented which helps to explain the interaction of both effects, shows a new way of minimizing the total dispersion by matching the two effects, and simplifies the calculation of pulse broadening in imperfect real fibers.
