摘要：
The self-similar propagation properties of optical waves in tapered power-law nonlinear materials with inter modal dispersion are investigated analytically. Our results show that the optical waves can be compressed to a predictable profile while maintain its original shape in both sech(2) and parabolic tapering profile nonlinear materials. The modulation of inter modal dispersion imposed on the propagation properties of optical waves is discussed. Furthermore, the stability of optical waves has also been tested by numerical simulations.
