| Abstract: | Aim To investigate large enhancement of the third-order nonlinearity in a four-level system with double dark resonances.Methods By using the dressed-state approach,an analytical expression for the linear susceptibility and nonlinear susceptibility of a weak probe field is obtained.Results and Conclusions It is showed that the properties of double electromagnetically induced transparency and the self-Kerr nonlinearity can be modified significantly by changing the ratio of the two coupling fields. |
