The goal of replacing electronics with optics for processing data in computers is coming closer through cutting edge European research into the mysterious properties of “fast and slow” light. The long term aim is to boost processing speeds and data storage densities by several orders of magnitude and take the information technology industry into a […]

Chemical engineers have developed a “self-assembling” method that could lead to an inexpensive way of making diamondlike crystals to improve optical communications and other technologies.
The method, developed at Purdue University, works by positioning tiny particles onto a silicon template containing precisely spaced holes that are about one-hundredth the width of a human hair. The template […]

University of Arizona optical scientists have broken a technological barrier by making three-dimensional holographic displays that can be erased and rewritten in a matter of minutes.
The holographic displays - which are viewed without special eyewear - are the first updatable three-dimensional displays with memory ever to be developed, making them ideal tools for medical, industrial […]
