| 摘 要： | 本文运用Kronig—Penney模型新形式,研究超晶格子带间光吸收的三阶非线性效应,发现不论量子阱参数(如阱宽、垒宽和垒高等)如何改变,光吸收饱和强度与隧穿谱宽之间存在着一种较普遍的关系,并阐明了这种依从关系的物理机制。

| Abstract: | By means of a new formalism of the Kronig-Penney model developed recently, the third order nonlinear optical effect of intersubband transitions in superlattices is studied. It is shown that there is a general relation between optical saturation intensity and tunnel bandwidth. The physical mechanism of this relation is analyzed. |
