电磁感应透明与Kerr非线性效应的增强
The electromagnetically induced transparency and enhanced Kerr nonlinearity effect
摘要
Abstract
A theoretical investigation of the effect of spontaneously generated coherence and the applied laser field intensity on the electromagnetically induced transparency and Kerr nonlinearity is carried out. It is found, with spontaneously generated coherence present, the Kerr nonlinearity can be clearly enhanced is carried out,and the maximal Kerr nonlinearity does not only enter the electromagnetically induced transparency window as the spontaneously generated coherence intensitifles, but also gets enhanced about 10 times with large SCC coefficients than that with no SCC effect. In addition, the enhanced Kerr nonlinearity can also be obtained by decreasing the ratio of the coupling field intensity to the control field intensity.关键词
