Polarization evolution in 3D micro-cavities — •Jakob Kreismann and Martina Hentschel — TU Ilmenau, Institut für Physik, Theoretische Physik II / Computational Physics, Weimarer Straße 25, 98693 Ilmenau

We investigate electromagnetic propagation in three-dimensional cone-shaped microtube cavities. In such a geometry, the polarization state of resonant whispering gallery modes may differ strongly from the reference case of homogeneous cylinders. In particular, we study how breaking of symmetries influences the morphology of resonances that can be associated with inclined trajectories. This is accompanied by the transition from linear to elliptical polarization. Eventually, we discuss the results from the point of view of spin-orbit interaction of light and its interpretation in terms of Berry phases.
