Controlling Optical Solitions in Self-focusing Kerr Medium by Adding Potential Barrier (Trap)
In order to control solitons in Kerr medium, based on Schrodinger equation, the optical soliton transmission in nonlinear self-focusing Kerr medium, after adding Gaussian-type potetial barrier, Gaussian-type potetial trap, Scarf-Ⅱ barrier (trap) and periodic potential barrier (trap), was studied by fast Fourier transform numerical simulation. The soliton can be controlled by changing the height (depth) of potential barrier (trap), the width of the gaussian-type barrier (trap) and Scarf-Ⅱbarrier (trap), or the period of the periodic potential barrier (trap). There are different phenomena in optical soliton transmission, such as tunneling, cyclical swings, linear transmission, division and so on, by selecting the different parameters. The study is available for cotrolling the soliton and optical switch and photocontrol.
