Design of a Dispersion-Managed Soliton in a Composite Left/Right-Handed Optical Fiber

Abstract

We study the propagation in a composite left/right-handed optical fiber. From the hypothesis of opposite refractive index, we show that the compensation between the anomalous dispersion due to the left-handed section and the normal dispersion due to the right-handed section can lead to a dispersion-managed soliton. This non conventional soliton is obtained under certain conditions including the lengths ratio and the length of the unit section of the metamaterial portion. It comes that modulations on the dispersion-managed soliton are negligible when the metamaterial section is smaller. The study is carried out using the collective variables approach which is an analytical method allowing to determine the evolution of a solitary wave parameters such as gaussian pulse used here.
