| Summary: | In this paper, a new modified direct similarity reduction method is considered to find new classes of Jacobi, hyperbolic and periodic wave solutions for both (1 + 1)-dimensional and (2 + 1)-dimensional nonlinear variable coefficients Schrödinger equations (vcNLSE) arising in optical fiber. Additionally, as a conclusion we have arrived in a theorem for both direct reduction and exact solutions to (n + 1)-dimensional vcNLSE. Finally, some physical applications for optical soliton propagation is given joint with figures. Keywords: Variable coefficients nonlinear Schrödinger equations, Modified similarity reduction method, Multiply Jacobi, Hyperbolic, periodic wave solutions
