摘要: 用最近所发展的产生函数(generating function)理论方法研究了单量子点在连续外场作用下光子发射的性质:光子发射强度,Mandel Q参数以及X与Y偏振光子之间的关联
在不同激发场强下随激发光场偏振方向的变化性质:在弱场激发下,激发场的强度决定了发射光子的特性;在强光场激发下,发射光子,Mandel Q参数和X偏振以及Y偏振光子的关联 都表现出比较复杂的非线性现象. Abstract: We studied the properties of the X-and Y-polarized photon emission from the single quantum dot system driven by external cw laser using the generating function approach developed recently.The results demonstrate that the X-and Y-polarized photon show sine or cosine behavior with the field direction in the weak field region.They show,however,stronger nonlinear behavior in the strong field region. -
