我们提出了一种新的方案来设计支持单向光发射的高Q值模式的光学微腔。这是通过将单向发射的低$Q$模式耦合到高$Q$模式来实现的。这种耦合是由于避免共振交叉附近的动态隧穿增强所致。带有适当位置气孔的微盘的数值结果证明了这一概念的可行性和潜力。
We introduce a new scheme to design optical microcavities supporting high-$Q$ modes with unidirectional light emission. This is achieved by coupling a low-$Q$ mode with unidirectional emission to a high-$Q$ mode. The coupling is due to enhanced dynamical tunneling near an avoided resonance crossing. Numerical results for a microdisk with a suitably positioned air hole demonstrate the feasibility and the potential of this concept.
