This paper studies the high-order coupled variable coefficient nonlinear Schrodinger equations and analytically obtains the double-hump soliton solutions. The interaction properties of double-hump solitons are discussed. The results are helpful for enhancing soliton intensity in fiber systems using dispersion decreasing fibers.
In this paper, the high-order coupled variable coefficient nonlinear Schrodinger equations is studied. The double-hump soliton solutions for the equations are obtained analytically. Double-hump solitons for the solutions are presented with different parameters. Interaction properties of double-hump solitons are discussed. Results are helpful to enhance the soliton intensity in fiber systems using the dispersion decreasing fibers.
