Emission directionality switching for chaotic dielectric cavitiesAlexander Eberspächer1, Jeong-Bo Shim1, •Jan Wiersig1, Hui Cao2, Brandon Redding2, Qinghai Song3, and Li Ge41Institut für Theoretische Physik, Otto-von-Guericke-Universität Magdeburg — 2Department of Applied Physics, Yale University — 3Harbin Institute of Technology — 4Princton University

The far-field emission directionality for ultra-small dielectric microcavities is discussed. For deformed microcavity systems, we found that tiny changes in boundary deformations—much smaller than the wavelength—can have drastic effects on the emission directionality of individual modes. Even though one expects that this change cannot be resolved by the optical modes, the far-field can switch directionality. We characterise the emission in terms of tunneling and demonstrate that the changes in boundary deformation induce considerable differences in the dynamical status of the systems under investigation. Then, the relation of dynamical status and emission will be discussed.
