| Abstract: | According to the core-cladding interface of an ideal waveguide as which a step-index fiber istaken,the transverse plane has been devided into two regions. Mode fields and propagation constantsof the graded-index optical fibers have been calculated by using regional waveguide mode expansionand coupled mode theory. |

| Keywords: | Optical fibers Mode field and Dropagation constant Regional waveguide mode: Coupledmode theory |
