Exploiting multiple scattering in random nanoparticles, we demonstrate focusing beyond the diffraction limit by controlling the far-field wavefront. In analogy with recent work in microwaves, we use elastic light scattering from a Subwavelength Light Focusing Using Random Nanoparticles. ????, ??? ?? ???? ????? ???. ? ?? ?? ??? ???? ????? ???. ??? ???? ????. ??? ?? ?? ?? ? ?? ??. ?? ??? ?? ?? ? ???? ?. ???. ??? ?? ? ???? ???. ?? ???? ??? Subwavelength light focusing using random nanoparticles. Nature photonics 2013, 7(6): 454-458. 14. Kaina N, Lemoult F, Fink M, Lerosey G. Negative refractive index and acoustic superlens from multiple scattering in single negative metamaterials. Nature 2015, 525(7567): 77-81. 15. Yu H, Park J, Lee K, Yoon J, Kim K, focus by obtaining subwavelength foci of the same size using random materials made of ZnO and commercial white paint field components by multiple light scattering from disordered nanoparticles, which we call “scattering super-lens", we achieve sub-wavelength light focusing by far-field wavefront control (Fig. 18 Dec 2017 Full-text (PDF) | There has been an escalation in interest in developing methods to control the near field because of its role in subwavelength optics. Many novel ideas have emerged in the field of plasmonics, super-resolution optical imaging and lithography, among others. However, the near field November 2014. Adaptive optics can focus light through opaque media by compensating the random phase delay resolution, gathering light on a spot with a diameter which is one third of the original speckle grain. The active control of .. Subwavelength light focusing using random Nanoparticles. Nature photonics 7,. 30 Jan 2017 Here, we experimentally demonstrate the time-reversal of a subwavelength optical focus containing near-field information, with far-field optical phase conjugation. A monochromatic optical field from a subwavelength light source was scattered by random nanoparticles, which effectively converted the Here, we demonstrate the regeneration of a subwavelength optical focus by phase conjugation. Monochromatic light from a subwavelength source is scattered by random nanoparticles, and the scattered light is phase conjugated at the far-field region by coupling its wavefront into a single-mode optical reflector using a Abstract: We demonstrate subwavelength light focusing using multiple scattering through complex media. novel schemes have been developed that allow sub-diffraction limited imaging using visible light [1].
