The conditions necessary for the amplitude or the temporal width of an N = 1 soliton to increase, remain constant, or decrease with distance on an axially nonuniform optical fiber are derived. Numerical results for a step-index fiber with an axially tapered core are presented. The effects of such a fiber on higher-order solitons are also presented.
