New York, N.Y., July 11, 2011 — In what is being touted as a major breakthrough in the field of telecommunications, scientists have built optical nanostructures that can slow down photons and fully control light dispersion. They have shown that it is possible for light to propagate from point A to point B without accumulating any phase, spreading through the artificial medium as if the medium is completely missing in space. This is the first time that simultaneous phase and zero-index observations have been made on the chip-scale and at the infrared wavelength. The nanofabricated superlattices, which consist of...Read full articleRelated content from Photonics MediaARTICLESWorking Remotely?

A typical optical delay line consists of a retroreflector or folding mirrors on...Photonics HandbookLaser Safety: Important Considerations: Laser safety is nothing to scoff at; lasers can be hazardous. Enter Class 1 laser products — lasers that are so safe that the user doesn’t require specific laser safety training or protective eyewear. Some precautions still exist, though.When purchasing an industrial laser system, the astute buyer will look for a Class 1 laser product — a system where the laser beam hazard is completely enclosed and there is no potential laser...Photonics HandbookAspheric Lenses: Design Considerations: This first of two articles will cover design and manufacturing options for aspheres; the second will include more detail on manufacturing and testing processes. These articles will provide the tools optics designers need to tailor their designs to the appropriate manufacturing process and to optimize the cost of component fabrication.Aspheric surfaces are powerful tools that combine the optical corrections of multiple lenses into a single element (Figure 1) and affect performance in ways that spherical optics cannot. For example,...Photonics HandbookFiber Optics: Understanding the Basics: Nothing has changed the world of communications as much as the development and implementation of optical fiber.
