【摘要】 利用微观运动方程计算了超快红外泵浦光引起的半导体双量子阱结构的子带间极化。基于自洽场理论 ,可以求出瞬态探测光吸收系数。这一方法没有采用稳态假设。计算了不同泵浦强度和泵浦探测延时的吸收系数。利用这一模型可以计算半导体微结构中的相干载流子的控制问题。更多还原

【Abstract】 The microscopic equations of motion including many-body effects were derived to study the intersubband polarization in the double quantum well structure induced by an ultrafast pumping infrared light. Based on the self-consistent field theory, the transient probe absorption coefficient was calculated. These calculations were beyond the previous steady-state assumption, Transient probe absorption spectra were calculated under different pumping intensity and various pump probe delay.更多还原
