摘要：

Multimode fibers with power-law index profiles achieve maximum bandwidth for a well-defined optimum value of the exponent α of the power-law function. Even slight sinusoidal fluctuations superimposed on the ideal power-law profile reduce the signal bandwidth of the fiber dramatically. It is shown in this paper that phase reversal of the sinusoidal fluctuation at the midpoint of the fiber leads to substantial compensation of the multimode time delay dispersion. This investigation proves that sinusoidal (and of course more general) perturbations superimposed on perfect power-law index profiles lead to less severe degradation of the fiber bandwidth if their phases vary as a function of the fiber length coordinate z. © 1979 Optical Society of America.
