A NOVEL METHOD FOR ANALYSIS OF SOLITON PROPAGATION IN OPTICAL FIBERS

We have proposed a new technique to analyze the propagation behavior o f solitons in an optical fiber. This technique is based on the Fourier series analysis technique (FSAT) which can consider fiber loss and th ird-order dispersion. Using this technique, the propagation of soliton s in an optical fiber has been investigated. The results compare well with the well-known split-step Fourier method (SSFM). We found that fo r a given computational accuracy, in order to obtain the same results, we need fewer sampling points for FSAT compared with the SSFM.
