The purpose of this article is to analyze the impact of an index segmentation on the ray dispersion in the geometrical approach. The presented study re- veals that a periodic index segmentation of the waveguide along with a trans- verse gaussian index variation exhibits complex ray dynamics that strongly modify ray dispersion properties.
