加工技术的进步，如量子阱结构和干蚀刻技术，使得创造新型的二维（2D）微腔激光器成为可能，尽管传统的一维（1D）边缘发射型激光器具有一维发射，但其输出激光具有二维发射模式。二维微腔激光器为与量子混沌密切相关的波混沌基础研究提供了良好的实验平台。新型二维微腔激光器还具有方向性和高功率输出光的重要激光特性，在光通信、集成光电路和光学传感器等领域有很好的应用前景。从经典混沌和量子混沌的角度回顾了二维微腔激光器的基本物理学，并介绍了近年来发展起来的理论方法。此外，还解释了波混沌模式通过有源激光介质相互作用所引起的非线性动力学。介绍了二维强光约束定向发射微腔激光器的应用，以及利用波混沌特性设计的高精度旋转传感器。
Advances in processing technology, such as quantum-well structures and dry-etching techniques, have made it possible to create new types of two-dimensional (2D) microcavity lasers which have 2D emission patterns of output laser light although conventional one-dimensional (1D) edge-emitting-type lasers have 1D emission. Two-dimensional microcavity lasers have given nice experimental stages for fundamental researches on wave chaos closely related to quantum chaos. New types of 2D microcavity lasers also can offer the important lasing characteristics of directionality and high-power output light, and they may well find applications in optical communications, integrated optical circuits, and optical sensors. Fundamental physics of 2D microcavity lasers has been reviewed from the viewpoint of classical and quantum chaos, and recently developed theoretical approaches have been introduced. In addition, nonlinear dynamics due to the interaction among wave-chaotic modes through the active lasing medium is explained. Applications of 2D microcavity lasers for directional emission with strong light confinement are introduced, as well as high-precision rotation sensors designed by using wave-chaotic properties.
