Spatiotemporal coupled-mode theory in dispersive media under a dynamic modulation
arXiv:1403.2905 · doi:10.1016/j.optcom.2014.03.040
Abstract
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 non-linear optical interactions involving a dynamic modulation of the interaction parameters such as non-reciprocal phenomena, time reversal of signals and spatiotemporal quasi phase matching
