Modifications of the phase space structure of optical microcavities due to the Goos-Hänchen shift — •Julia Unterhinninghofen1, Jan Wiersig1, and Martina Hentschel2 — 1Institut für theoretische Physik, Universität Bremen, Postfach 330 440, 28334 Bremen — 2Max-Planck-Institut für Physik komplexer Systeme, Nöthnitzer Str. 38, 01187 Dresden
Optical microcavities have important applications in various different fields of physics [1]. In the quantum chaos community microdisk cavities with deformed cross-sectional shape attracted considerable attention since they can be used to study the ray-wave correspondence in open systems in direct comparison to experiments [2,3]. As recent experimental progress allows for smaller and smaller cavities, wave corrections to the ray dynamics become highly relevant. We theoretically study the influence of the most important correction, the Goos-Hänchen shift [4], on the phase space structure of optical microcavities. We find an interesting relation to scarlike modes near avoided resonance crossings [5].
