Controlling Kerr nonlinearity with electric fields in asymmetric double quantum-dots
arXiv:0801.3726
Abstract
The control of Kerr nonlinearity with electric fields in an asymmetric double quantum-dot systems coupling with tunneling is investigated theoretically. It is found that,by proper tuning of two light beams and tunneling via a bias voltage, the Kerr nonlinearity can be enhanced and varied within a wide scale.
