This chapter discussed an accurate and powerful semiclassical multiphysics approach to numerical modeling of several critical nonlinear phenomena employing carrier kinetics. We conclude that coupling a system of multilevel rate equations with Maxwell's equations provides a versatile full-wave framework with significantly enhanced predictive power that is capable of simulating sophisticated nanostructured photonic and optoelectronic devices with embedded nonlinearities and vectorial input beams of arbitrary spatiotemporal complexity.
