Microstar cavities: An alternative concept for the confinement of light — •Julius Kullig1, Xuefeng Jiang2, Lan Yang2, and Jan Wiersig11Institut für Physik, Otto-von-Guericke Universität Magdeburg, Magdeburg, Germany — 2Department of Electrical and Systems Engineering, Washington University in St. Louis, St. Louis, USA

We report on a novel concept to confine light in a microcavity. In contrast to traditional approaches we exploit neither total internal reflection nor a photonic band gap. Our approach is rather based on the perfect transmission of light at Brewster's angle. Thus, in a properly designed star-shaped cavity light rays can sequentially leave and reenter the cavity along a periodic orbit without loss of intensity. Accordingly, in the wave dynamics long-lived optical modes arise with fascinating and unique properties.
