For the dispersion-optimized range of power-law refractive-index profiles in optical fibers, the phase and the eigenvalue integrals appearing in Wentzel-Kramers-Brillouin solutions are solved. These new solutions provide an explicit description of the electromagnetic-field distributions and phase constants in weakly guiding fibers with power-law refractive-index profiles in terms of usual fiber parameters.
