The Effect of Gain and Strong Dissipative Structures on Nonlinear Schrödinger Equations in Optical Fiber

We consider the initial value problem for the nonlinear Schrödinger equation satisfying the strong dissipative condition I λ < 0 and I λ > p - 1 / 2 p R λ in one space dimension. Our purpose in this paper is to study how the gain coefficient μ ( t ) and strong dissipative nonlinearity λ v p - 1 v affect solutions to the nonlinear Schrödinger equation for large initial data. We prove global existence of solutions and present some time decay estimates of solutions for large initial data.
