Propagation Modes in Multimode Graded-Index Fibers

Zaman Hameed Kareem, Ali Hadi Hassan, Hassan Abid Yasser

Abstract: In this research some important parameters of graded index fiber have been studied such as numerical aperture, the normalized frequency and their effects on the modal dispersion. The modal dispersion and the propagation delay have been calculated and plotted as functions of radial number and azimuthal number.
