Higher order dispersion measurement using the stationary phase point method

A detailed investigation regarding the applicability of the stationary phase point method in higher-order dispersion measurement is presented. The cases of dominant second-, joint second- and third-, dominant third- and dominant fourthorder dispersion were studied using simulations. We have come to the conclusion that the stationary phase point method is suitable for dispersion retrieval when the group-delay dispersion or the third-order dispersion term is the dominant, however, it became inaccurate in the presence of dominant fourth-order dispersion as the stationary phase point spread. The results obtained by simulation were compared with measurements performed on a second-order reduced, third-order dominant fiber sample. We found good agreement between simulations and the measurements.
