Unidirectional light emission from high-Q modes in optical microcavities
arXiv:cond-mat/0512435 · doi:10.1103/PhysRevA.73.031802
Abstract
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.
