SOLITONS: NOVEL APPROACH FOR DISPERSION MANAGEMENT

Suruchi Bala, Anu Sheetal

Abstract: Soliton is a special kind of wave packet that travels distortion less over long distances. It is a pulse able to maintain its shape and width due to compensation of Self Phase Modulation (SPM) process which is a non-linear effect based on refractive index variation and Group Velocity Dispersion (GVD) process which is a linear effect. For long range communication, soliton pulses are very suitable as the pulse width remain constant over the entire transmission distance. It eliminates the need to cope with any type of dispersion. The transmission of light in optical fiber given by Nonlinear Schrödinger equation has been discussed in the paper. The performance of fiber with soliton parameters is compared to that with fiber without soliton parameters using OptiSystem Software.
