Hazen: Super-Oscillation Papers

  • Rogers et al Nature Material, 2012
  • replace lens with a diffraction grating pattern. – bright external ring, central spot less than diffraction size (185 nm)
  • resolve two slits separated by 140 nm.
  • super-oscillations — Functions with only 5 Fourier modes can have tiny features with FWHM much smaller than the smallest Fourier wavelength.
