Holographic approach to phase conjugation of optical near fields

Abstract:

Phase conjugation of optical dipole fields is considered in a static holographic scheme with totally internally reflected reference and reconstruction waves. It is shown that as the distance between the dipole object and the recording medium decreases from the far- to the near-field region, the intensity distribution of the reconstructed dipole field changes from a diffraction-limited light spot to a subwavelength-sized light spot that is brightest at the surface of the hologram. The influence of the thickness of the recording medium, the angle of incidence of the reconstruction wave, and the polarization configuration on the reconstructed intensity distribution are also discussed.
