Modification model of soliton pulse for higher order

Abstract

In this paper the variation in soliton pulse with different order number (N) has been investigated and analyzed by Nonlinear Schrodinger Equation (NLSE). The Split-Step Method has used for numerical calculation. The change in pulse shape, the slight decrease in power level and dispersion has been observed with increase in the soliton pulse order number. Thus, the soliton pulse parameters can be optimized to acquire the desired output. By using a half-soliton period length of low-loss single-mode fiber, we have been able to demonstrate the pulse compression and pulse splitting associated with several higher-order soliton as well as to observe the fundamental soliton.
