Goos-Hänchen shift and Fresnel filtering at curved interfaces - Analytic and numeric results — •Pia Adam, Jakob Kreismann, and Martina Hentschel — Technische Universität Ilmenau, Institut für Physik, Ilmenau, Germany

Describing confined light bundles by rays obeying the laws of geometrical optics is a powerful tool even in the regime where, strictly speaking, full wave dynamics should be applied. When considering structures at length scales of a few wavelengths, however, semiclassical effects have to be taken into account. These deviations from the laws of geometrical optics are the Goos-Hänchen shift which is long known for planar interfaces, and the Fresnel filtering effect. In this work we derive analytical expressions to describe the Goos-Hänchen shift and Fresnel filtering at curved interfaces in the regime of total reflection as well as for partial reflection. These analytical results are supported by numerical simulations.
