The procedure, described today in the journal Optics Express, cuts the production time of hollow-core optical fibres from around a week to a single day, reducing the overall cost of fabrication.

Researchers at the University of Illinois are the first to achieve optical waveguiding of near-infrared light through features embedded in self-assembled, three-dimensional photonic crystals.

Smaller, faster, more efficient: BASF research scientists are helping to revolutionize the future world of telecommunications – with the aid of three-dimensional photonic crystals.

Imagine cleaning out your refrigerator and being able to tell at a glance whether perishable food items have spoiled, because the packaging has changed its color, or being able to tell if your dollar bill is counterfeit simply by stretching it to see if it changes hue.

University of California, Riverside nanotechnologists have succeeded in controlling the color of very small particles of iron oxide suspended in water simply by applying an external magnetic field to the solution.
