Perturbative analysis of whispering-gallery modes in the Limaçon microcavity — •Marcus Kraft and Jan Wiersig — Otto-von-Guericke-Universität Magdeburg, 39016 Magdeburg

In recent experiments it has been demonstrated that wavelength-scale microdisk lasers with the shape of a Limaçon can support high-quality whispering-gallery modes despite the chaotic internal ray dynamics. Here, we show that these modes can be accurately described by a perturbation theory for slightly deformed microdisk cavities. Our results reveal that the performance of the perturbation theory can be considerably improved by a suitable choice of the origin around which the perturbation series is expanded.
