利用避免的共振交叉研究了非对称谐振腔中的动态隧穿现象。与外部耦合共振定位在不同区域的相空间，我们表明，隧道速率可以显着降低。在两态弱耦合下，几乎完全抑制了动力学隧穿，即所谓的“锁定”。提出了一种实验观测和控制动态隧穿相干破坏的可能途径。我们的研究可能会在微腔激光器的调Q和超快光束控制中得到应用。DOI：10.1103/PhysRevA.87.013831
The phenomenon of dynamical tunneling is investigated in asymmetric resonant cavities by exploiting the avoided resonance crossing. With the external coupling between resonances localized within different regions of phase space, we show that the tunneling rate can be dramatically reduced. The nearly complete suppression of dynamical tunneling, so-called "locking," has been achieved under two-state weak coupling. A possible way to observe and control the coherent destruction of dynamical tunneling experimentally is also presented. Our research may find application in Q switching and ultrafast beam steering of microcavity lasers. DOI: 10.1103/PhysRevA.87.013831
