Beschreibung

In optical microcavities dynamical tunneling leads to finite lifetimes of whispering gallery modes, which are classically confined by total internal reflection. The lifetimes of such modes may drastically decrease by resonance-assisted tunneling due to the presence of classical non-linear resonances in the ray dynamics. We extend the description of resonance--assisted tunneling from near-integrable systems to systems with a mixed phase space showing regular as well as chaotic dynamics. In particular, we present a semiclassical description based on ray dynamics. This provides an intuitive picture depending only on classical properties, which is in good agreement with numerical solutions to the mode equation. Further we combine these methods with a perturbative approach resulting in an equally accurate quantitative prediction of lifetimes and quality factors.
