  • Until now, invisibility cloaks have only covered a region of a few wavelengths because of their nanostructured materials. Chenet al.describe a macroscopic cloak, made of calcite birefringent crystals, which works for a specific polarization at visible wavelengths.

  • A temporal version of Young’s double-slit experiment shows characteristic interference in the frequency domain when light interacts with time slits produced by ultrafast changes in the refractive index of an epsilon-near-zero material.

  • The maximum imaging resolution in classical optics is limited to approximately the wavelength of light used, and subwavelength resolution can only be achieved by advanced imaging schemes. The appeal of the super-oscillatory lens optical microscope described here is that it enables subwavelength imaging with, in principle, unlimited resolution using a modified conventional microscope.

  • A planar composite material images ultraviolet light like a lens, by unwinding its phase. The concept could aid high-resolution nanolithography.

  • An illusion device, placed near but not enclosing an object of arbitrary shape, manipulates and transforms light scattered off the object so as to give it the appearance of a completely different object.

  • Indium Tin Oxide thin films exhibit ultrafast optical switching of permittivity. Here, the authors demonstrate a change in nonlinear optical properties of the material, and a modulation of harmonic generation.

  • Ordinary materials have their index ellipsoids centered at zero momentum. The authors propose a metamaterial of interpenetrating wire meshes whose connectivity can be used to control the number and position of index ellipsoids at arbitrary nonzero k-points. This could provide a new platform for broadband functionality.

  • An artificially created material with negative refractive index has opened the door to new phenomena — and controversy. New work finally sets the seal of experimental confirmation on negative refraction.

  • Artificial materials composed of either structured or random subunits far below the wavelength of light can be designed to display fascinating physical properties. Recent advances in fabrication technology have established the great potential of such metamaterials for applications.
