【 摘 要 】

A simple and general formalism for mode coupling by a spatial, temporal or spatiotemporal perturbation in dispersive materials is developed. This formalism can be used for studying various linear and nonlinear optical interactions involving a dynamic modulation of the interaction parameters such as nonreciprocal phenomena, time reversal of signals and spatiotemporal quasi-phase matching.
