TL;DR: In this article, the authors describe an all-angle negative refraction effect that does not employ a negative effective index of refraction and involves photonic crystals, and demonstrate this phenomenon using a microsuperlens.
Abstract: We describe an all-angle negative refraction effect that does not employ a negative effective index of refraction and involves photonic crystals. A few simple criteria sufficient to achieve this behavior are presented. To illustrate this phenomenon, a microsuperlens is designed and numerically demonstrated.

TL;DR: In this paper, the authors presented the design and experimental realization of strongly coupled optical and mechanical modes in a planar, periodic nanostructure on a silicon chip, where 200-Terahertz photons are co-localized with mechanical modes of Gigahertz frequency and 100-femtogram mass.
Abstract: Structured, periodic optical materials can be used to form photonic crystals capable of dispersing, routing, and trapping light A similar phenomena in periodic elastic structures can be used to manipulate mechanical vibrations Here we present the design and experimental realization of strongly coupled optical and mechanical modes in a planar, periodic nanostructure on a silicon chip 200-Terahertz photons are co-localized with mechanical modes of Gigahertz frequency and 100-femtogram mass The effective coupling length, which describes the strength of the photon-phonon interaction, is as small as 29 microns, which, together with minute oscillator mass, allows all-optical actuation and transduction of nanomechanical motion with near quantum-limited sensitivity Optomechanical crystals have many potential applications, from RF-over-optical communication to the study of quantum effects in mesoscopic mechanical systems

TL;DR: In this article, a general perspective is presented on the state of the art in photonic crystals (PCs) providing a broad audience-oriented description of fundamentals and properties, as well as a broad overview of photonic bandgap (PBG) materials.
Abstract: Photonics, the technology of photons (as electronics is the technology of electrons), promises to be the new century's driving force in the advancement of, mainly but not only, information technology, such as communications and computing. This technology was initiated with the advent of lasers and optical fibers that, for various reasons, embody the best choice of source and channel of the information carrier: the photon. If the parallel with electronics is to be further pursued, one soon realizes that many more components are needed not only in the transport section of the technology but also, and principally, in the logic section: signal processing. An answer is promised to many of these demands by the potentiality of the new photonics era: photonic bandgap (PBG) materials, otherwise known as photonic crystals (PCs). In the present review a general perspective is presented on the state of the art in PC technology providing a broad audience-oriented description of fundamentals and properties.

TL;DR: Based on spectral measurements of the polarization mode beating, it is estimated that the strongly anisotropic photonic crystal fiber has a beat length of approximately 0.4 mm at a wavelength of 1540 nm, in good agreement with the results of modeling.
Abstract: We report a strongly anisotropic photonic crystal fiber. Twofold rotational symmetry was introduced into a single-mode fiber structure by creation of a regular array of airholes of two sizes disposed about a pure-silica core. Based on spectral measurements of the polarization mode beating, we estimate that the fiber has a beat length of approximately 0.4 mm at a wavelength of 1540 nm, in good agreement with the results of modeling.
