Abstract :
The influence of irregular index profiles on waveguide dispersion, cutoff wavelength, and modal field diameter in monomode fibers is studied systematically. The authors present an analytical theory, which relies on the fact that for a broad family of profiles (those which contain a term proportional to r-2) the wave equation can be solved exactly. The influence of profile details on dispersion appears to be larger than previously expected
