Abstract

Based on the recently reported generalized projection operator method for nonlinear Schrödinger equation, one can derive two different sets of pulse parameters equations while using ansätze like hyperbolic secant or raised-cosine. We show that in case of a Gaussian like ansatz those sets of equations are unique because of the symmetric property between the ansatz parameters.
