Query: Third-order Exceptional Point and Successive Switching among Three
  States in a Degenerate Optical Microcavity   One of the most intriguing topological features of open systems is exhibiting
exceptional point (EP) singularities. Apart from the widely explored
second-order EPs (EP2s), the explorations of higher-order EPs in any system
requires more complex topology, which is still a challenge. Here, we encounter
a third-order EP (EP3) for the first time in a simple fabrication feasible
gain-loss assisted optical microcavity. Using scattering-matrix formalism, we
study the simultaneous interactions between three successive coupled states
around two EP2s, which yield an EP3. Following an adiabatic parametric
variation around the identified EP3, we present a robust
successive-state-conversion mechanism among three coupled states. The proposed
scheme indeed opens a unique platform to manipulate light in integrated
devices.
