Transient Gratings, Four-Wave Mixing and Polariton Effects in Nonlinear Optics
Abstract
Nonlinear optical susceptibilities provide a convenient means of relating macroscopic optical measurements to microscopic models. The susceptibilities are useful as long as the radiation field and the material degrees of freedom are weakly coupled. In the opposite case, the dynamics is interpreted in of combined radiation-nmw modes (polaritons) and susceptibilities are usually not used. In this review we analyze both situations from a unified dynamical framework based on equations of motion. The present formalism is also particularly suitable for the calculation of optical nonlinearities in nanostructures with restricted geometries. The transient grating and its frequency-domain analogue (degenerate four wave mixing) are used to illustrate the formalism in both the strong and the weak radiation-matter coupling limit.
