We investigate the enhanced Kerr nonlinearities in four-levelatomic vapors driven by a coupling, probe and microwave fields.Under the optical one-photon and two-photon resonant conditions, thelinear and nonlinear responses of the weak probe field can bemodified by the cross talk among optical and microwave transitions.The enhanced Kerr nonlinearity can form bright optical solitons of the probe field. |
