【Abstract】 By using the fractional transformation method, the exact solutions of the higher-order nonlinear Schrodinger equation are obtained which included Jacobian elliptic function solution and new solitary wave solution. This equation is used to describe the progation of femtosecond optical pulses in fibers. Moreover it is pointed out that the new bright solitary wave exists in positive third-order dispersion regime.更多还原
