3.1 Coupled-Mode Dynamics in Nonlinear Optical Systems

In many instances, theoretical advances in nonlinear science result from universal descriptions from which knowledge can be transferable and even expanded into many fields. A good example closely connected to nonlinear optics and well supported by several chapters in this book and in the nonlinear optics literature is the case of quasi-monochromatic weakly nonlinear wave phenomena which is well described by the nonlinear Schrödinger equation (NLSE) and close “cousins.” Similarly, when the dynamics is still weakly nonlinear, but instead energy flows between two or more modes coupled by some resonant ...
