| 摘 要： | 运用Kronig-Penney(KP)模型的新形式,研究半导体超晶格中子带间跃迁的光学双稳特性。由二子能带模型密度矩阵方法,导出了子带间光跃迁的Maxwell-Bloch(MB)方程。从MB方程的定态解出发,得到了环形腔中超晶格子带间跃迁的光学双稳态方程,进而讨论了这种光学双稳的特点以及实现的条件。

| Abstract: | The optical bistability (OB) of intersubband transitions in a semiconductor superlattice is stu -died by applying the general formalism of the Kronig-Penney model and density matrix method. The Maxwell-Bloch (MB) equations of two-subband model are derived, and the OB state equation for a ring cavity is obtained from the stationary solution of the MB equations. The conditions for realizing the OB and its characteristics are discussed. |
