In optical microcavities dynamical tunneling allows for 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 nonlinear resonances of the ray dynamics. We present a fully semiclassical description of resonance-assisted tunneling in deformed optical microdisks based on a generalization of the theory for quantum maps. This provides an intuitive ray-based picture of resonance-assisted tunneling and spoiling of Q-factors using only classical phase-space properties.
