Light Controlling Light with Enhanced Kerr Nonlinearity
Min Xiao, Hai Wang, David J. Goorskey
The Kerr nonlinear index of refraction of a three-level atomic medium can be greatly enhanced by atomic coherence induced by two laser beams. Such electromagnetically induced transparency (EIT) media can be used to generate efficient nonlinear optical processes at low light intensities. Control and enhancement of Kerr nonlinearity in EIT media can be useful in all-optical communication, all-optical computing, and quantum information processing.
