BreviaFar-Field Optical Hyperlens Magnifying Sub-Diffraction-Limited Objects
The diffraction limit of light, which is causd by the loss of evanescent waves in the far field that carry high spatial frequency information, limits the resolution of optical lenses to the order of the wavelength of light. We report experimental demonstration of the optical hyperlens for sub-diffraction-limited imaging in the far field. The device magnifies subwavelength objects by transforming the scattered evanescent waves into propagating waves in an anisotropic medium and projects the high-resolution image at far field. The optical hyperlens opens up possibilities in applications such as real-time biomolecular imaging and nanolithography. 5130 Etcheverry Hall, NSF Nanoscale Science and Engineering Center (NSEC), University of California, Berkeley, CA 94720–1740, USA. * These authors contributed equally to this work.
