摘要

This paper analyzes spatial grey self-similar solitary waves propagation and collision in graded-index nonlinear waveguide amplifiers with self-focusing and self-defocusing Kerr nonlinearities.New exact self-similar solutions are found using a novel transformation and their main features are investigated by using direct computer simulations.
