Sub- and superdiffractive resonators with intracavity photonic crystals

Abstract

We investigate experimentally and theoretically plane-mirror Fabry-Perot resonators filled by photonic crystals, i.e., with periodic intracavity refraction index modulation. We show that the diffraction properties of such resonators can be manipulated, resulting in sub- and superdiffractive dynamics of light in the resonator, and in hyperbolic angular transmission profiles.
