Analysis of optical soliton propagation in birefringent fibers

Polarization mode dispersion (PMD) is a serious impairment in high-bit-rate optical soliton communication systems. This paper presents a detailed investigation of soliton pulse propagation in randomly varying birefringent optical fibers and how solitons broaden in presence of third order dispersion. Fiber birefringence is the physical origin of PMD. It is found that the third-order dispersion in the fibers is strong enough to cause the pulse distortion. In this paper we propose optical soliton propagation in birefringent single mode fibers with a new stochastic model in which the stochastically varying birefringence and third order dispersion are considered.
