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.
