“…The reconstruction of the sample features based on the measured optical information, the inverse scattering problem, can be facilitated by tuning the angle of incidence of the total internally reflected wave (Garcia and Nieto-Vesperinas, 1995). Several groups have theoretically established that PSTM measurements are inherently holographic and that they provide enough information to determine the two dimensional structure of a thin sample Bozhevolnyi and Vohnsen, 1996;Carney, 2004). A series of related studies on near-field phase conjugation have been performed by Sergey I. Bozhevolnyi and coworkers (Bozhevolnyi, 1994(Bozhevolnyi, , 1995.…”

“…Studies of near-field inverse scattering have been pursued by different groups, mainly using the PSTM geometry (Garcia and Nieto-Vesperinas, 1995;Bozhevolnyi and Vohnsen, 1996;Car-ney and Schotland, 2003). It was shown that samples can be uniquely reconstructed from near-field optical measurements by use of near-field tomography (Carney, 2004).…”

This article provides a review of early work and developments in the field of near-field optics. The roots trace back to the letters exchanged between Edward Hutchinson Synge and Albert Einstein in 1928 and, because of the analogy to antenna theory and lightning rods, the origins project back to the time of Benjamin Franklin who discovered the wonderful Effect of Points both in drawing off and throwing off the Electrical Fire. The modern interest was mainly inspired by the invention of scanning probe microscopy and by the first optical near-field measurements by Dieter W. Pohl and co-workers at the IBM Research Laboratory in Rüschlikon, Switzerland, and also by parallel developments of other groups. Near-field optics received inspiration from the fields of surface enhanced spectroscopy and from studies of energy transfer. While optical near-fields were extensively exploited for overcoming the diffraction limit in optical imaging the study of their physical aspects revealed unique properties which cannot be imitated by free propagating radiation.

Solid-state lighting relies on the conversion of electricity to visible white light using solid materials. By taking advantage of direct electricity-to-light conversion rather than processes in which light is the by-product of another conversion, as with traditional incandescent and fluorescent lighting, it promises unprecedented, near-100% conversion efficiency.Today's solid-state lighting technology, however, requires a fifteen-fold improvement to achieve such conversion efficiencies. The reason is that, to become the standard light source of the 21st century, conversion efficiency must be improved while simultaneously achieving low cost and "high quality" (a human visual experience similar to that provided by sunlight).The front cover is an artistic stylization of a "chromaticity diagram," a common tool that can be used to describe how colors can combine to create the human visual impression of white.White can be produced from as few as two colors, but "highquality" white requires many (e.g., red, yellow, green, and blue) colors. The tessellation overlaid on the chromaticity diagram is suggestive of photonic crystals (nanometer-scale periodic modulations of optical materials that can affect the directionality of light), a frontier area of interdisciplinary science being applied to solid-state lighting.This report outlines basic research needs that could enable solid-state lighting to achieve its potential. The research needs support two overarching challenges: (1) fundamental understanding of light-emitting materials and nanostructures leading to solid-state lighting structures rationally designed from the ground up and (2) control of the competing pathways by which electricity is converted into light not heat so that every injected electron produces a useful photon. Successfully addressing these two challenges promises to enable energy-efficient, cost-effective, high-quality white light that will save energy and benefit the environment. BASIC RESEARCH NEEDS FOR SOLID-STATE LIGHTING EXECUTIVE SUMMARYSince fire was first harnessed, artificial lighting has gradually broadened the horizons of human civilization. Each new advance in lighting technology, from fat-burning lamps to candles to gas lamps to the incandescent lamp, has extended our daily work and leisure further past the boundaries of sunlit times and spaces. The incandescent lamp did this so dramatically after its invention in the 1870s that the light bulb became the very symbol of a "good idea."Today, modern civilization as we know it could not function without artificial lighting; artificial lighting is so seamlessly integrated into our daily lives that we tend not to notice it until the lights go out. Our dependence is even enshrined in daily language: an interruption of the electricity supply is commonly called a "blackout."This ubiquitous resource, however, uses an enormous amount of energy. There is ample room for reducing this energy and environmental cost. The artificial lighting we take for granted is extremely inefficient primarily because a...

“…In fact, this is the fundamental principle of the near-field scanning optical microscopy (NSOM) where optical nanoantennas such as plasmonic nanoparticles or metallic tips are used. Considerable studies have been devoted to interpret the far-field signals [17][18] [19][20] [21] depending of the NSOM configuration, and images with resolution down to 10nm have been demonstrated possible. Nevertheless, NSOM do not project a physical image as a conventional lens does, and the slow scan speed prevents a dynamic imaging [22], often of practical importance.…”

Theory of optical imaging beyond the diffraction limit with a far-field superlens

et al. 2006

View full text Add to dashboard Cite

Recent theoretical and experimental studies have shown that imaging with resolution well beyond the diffraction limit can be obtained with so-called superlenses. Images formed by such superlenses are, however, in the near field only, or a fraction of wavelength away from the lens. In this paper, we propose a far-field superlens (FSL) device which is composed of a planar superlens with periodical corrugation. We show in theory that when an object is placed in close proximity of such a FSL, a unique image can be formed in far-field. As an example, we demonstrate numerically that images of 40 nm lines with a 30 nm gap can be obtained from far-field data with properly designed FSL working at 376nm wavelength.
