Ray engineering from chaos to order in two-dimensional optical cavities

  title={Ray engineering from chaos to order in two-dimensional optical cavities},
  author={Chenni Xu and Li-Gang Wang and Patrick Sebbah},
Chaos, namely exponential sensitivity to initial conditions, is generally considered a nuisance, inasmuch as it prevents long-term predictions in physical systems. Here, we present an easily acces-sible approach to undo deterministic chaos and tailor ray trajectories in arbitrary two-dimensional optical billiards, by introducing spatially varying refractive index therein. A new refractive index landscape is obtained by a conformal mapping, which makes the trajectories of the chaotic billiard…
