Microcavities with Brewster-notches: A concept for light confinement without reflection — •Julius Kullig and Jan Wiersig — Institut für Physik, Otto-von-Guericke-Universität Magdeburg, Magdeburg, Germany

We report on an interesting 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 which can be for particular interest, e.g., for sensing applications.
