NONLINEAR DYNAMICS AND INSTABILITIES OF COUPLED WAVES AND SOLITONS IN OPTICAL FIBERS

摘要: We review the dynamics of mode coupling in anisotropic and nonlinear optical fibers waveguides. On basis several specific examples, we focus our attention here on qualitative properties conservative equations describing spatiotemporal evolution field. In nondispersive limit, leads to parametric instabilities coexistence both regular chaotic energy exchange among modes. The geometrical viewpoint may also provide considerable physical insight dispersive regime propagation. fact, much behavior solitons modulated waves often be captured by truncations few degrees freedom.
