“…12 (a). [183][184][185] This lens can be thought of as operating similarly to structured illumination microscopy, 186 where moiré fringes are formed at the spatial frequency difference between an object field and incident patterned illumination. In the case of the FSL, the patterned illumination is replaced by a grating with grating wavenumber Λ.…”

Near-field optics and superlenses for imaging beyond Abbe's diffraction limit are reviewed. A comprehensive and contemporary background is given on scanning near-field microscopy and superlensing. Attention is brought to recent research leveraging scanning near-field optical microscopy with superlenses for new nano-imaging capabilities. Future research directions are explored for realizing the goal of low-cost and high-performance sub-diffraction-limited imaging systems. © 2016 Author(s)

“…7 A properly designed grating can translate a range of evanescent waves into the propagating regime, enabling them to propagate into the far-field region. Once detected in the far-field region, the grating-translated evanescent waves can be Fourier transformed back to the original Fourier components so that the image can be properly reconstructed.…”

Index of refraction, a fundamental optical constant that enters in the descriptions of almost all optical phenomena, has long been considered an intrinsic property of a material. However, the recent progress in negative-index material (NIM) research has shown that the utilization of deep-subwavelength-scale features can provide a means to engineer fundamental optical constants such as permittivity, permeability, impedance, and index of refraction. Armed with new nanofabrication techniques, researchers worldwide have developed and demonstrated a variety of NIMs. One implementation uses a combination of electric and magnetic resonators that simultaneously produce negative permittivity and permeability, and consequently negative refractive index. Others involve chirality, anisotropy, or Bragg resonance in periodic structures. NIM research is the beginning of new optical materials research in which the desired optical properties and functionalities are artificially generated. Clearly, creating negative index materials is not the only possibility, and the most recent developments explore new realms of materials with near-zero indexes and inhomogeneous index profiles that can produce novel phenomena such as invisibility. Furthermore, the concept of controlling macroscopic material properties with a composite structure containing subwavelengthscale features extends to the development of acoustic metamaterials. By providing a review of recent progress in NIM research, we hope to share the excitement of the field with the broader materials research community and also to spur new ideas and research directions.

“…Such negative-index media came out as seminal to the metamaterials field because of the vision of the "perfect lens" [3], where a slab of an artificial material with n = −1 (a "superlens") would focus light tighter than diffraction would allow in a conventional optical system. Even though this "perfect lens" dream, which hinges on the existence of lossless and isotropic negative-index metamaterials, may never come true, it did give birth to the entire field of study with several convincing experimental demonstrations of subwavelength imaging [4][5][6][7]. It was understood that the operating principle of the superlens is its ability to transmit, rather than to lose, the near-field information about a subwavelength object [8], as seen in Figs.…”

Abstract:We propose a device for subwavelength optical imaging based on a metal-dielectric multilayer hyperlens designed in such a way that only large-wavevector (evanescent) waves are transmitted while all propagating (small-wavevector) waves from the object area are blocked by the hyperlens. We numerically demonstrate that as the result of such filtering, the image plane only contains scattered light from subwavelength features of the objects and is completely free from background illumination. Similar in spirit to conventional dark-field microscopy, the proposed dark-field hyperlens is shown to enhance the subwavelength image contrast by more than two orders of magnitude. These findings are essential for optical imaging of weakly scattering subwavelength objects, such as real-time dynamic nanoscopy of label-free biological objects. References and links 1. W.
