Abstract
Emission characteristics of an oval-shaped microcavity laser are studied. In experiments, modes localized on periodic orbits emit unidirectionally with a narrow inplane divergence angle of about 12 degrees. The origin of high directionality is elucidated by means of classical ray dynamics. Wave calculations show that the Qfactors of the resonances are higher than 108 . We explain this extraordinary high-Q factor in relation with a dynamical barrier region where Kolmogorov-ArnoldMoser curves significantly obstruct leakages of resonances. © 2018 Optical Society of America
