H. Ghafourishiraz et al., A NOVEL METHOD FOR ANALYSIS OF SOLITON PROPAGATION IN OPTICAL FIBERS, IEEE journal of quantum electronics, 31(1), 1995, pp. 190-200
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.
