Dynamics of optical rogue waves in inhomogeneous nonlinear waveguides
【摘要】：We propose a unified theory to construct exact rogue wave solutions of the (2+1)-dimensional nonlinear Schrdinger equation with varying coefficients. And then the dynamics of the first- and the second-order optical rogues are investigated. Finally, the controllability of the optical rogue propagating in inhomogeneous nonlinear waveguides is discussed. By properly choosing the distributed coefficients, we demonstrate analytically that rogue waves can be restrained or even be annihilated, or emerge periodically and sustain forever. We also figure out the center-of-mass motion of the rogue waves.
