英文摘要： To settle the problem of the manipulation for optical rogue waves in nonlinear media, the multi variable self-similar method is used to explore the control mechanism of optical rogue wave with the external potentials. By proposing the concept of quantum parameter control of the system, the traditional diffraction and nonlinear management is changed into system quantum parameter control, and we will obtain a series of control methods. Through the coupling effect of incoherent multiple beams, the interaction of multi optical rogue waves and their energy conversion process are revealed, to achieve the goal of a beam controlling another one in the specific potentials, so that there is a new breakthrough in the development of all optical devices. The establishment of the control model of the optical rogue wave in nonlinear media, the acquisition of the exact solution, the numerical calculation are studied. The main contents include: (1) A nonlinear model of optical rogue wave is established. (2) The exact solution of the nonlinear model with the spatial diffraction, nonlinear modulation coefficient and the external potentials are obtained. And a series of controllable methods of the system for the quantum parameter of the system are generated. (3) We use numerical simulation and experiment to verify the correctness of the theoretical results. The project further extends the research field of nonlinear science. The obtained controllable methods provides a new theoretical guide for all optical devices, such as all-optical switches and all-optical cross connectors.
