Guiding light - CMD19/CMMP with The Physics Congress 2002
A new type of optical material has been developed by physicists that could replace the electronics used to route the light signals through optical fibre telecommunications networks. It could even provide the basis for future `optical computers` working on light pulses instead of electric signals.... view more (2002-03-26)

Butterflies' wings dazzle with science
The brilliant dazzle of butterflies' wings could hold the key to a new type of optical material, called photonic crystals. Over the past 15 years, photonic crystals have attracted the attention of a vast international community, as scientists have begun to realise their potential applications in... view more (2004-11-04)

Photonic Crystals in 3-D - The Physics Congress 2003
Telecoms systems contain an awkward mixture of optics and electronics. A purely optical system would permit the very high data rates needed by the Internet, but at the moment the switching and routing, as well as the "last mile" to the customer, still depend on slower electronic... view more (2003-03-17)

Bristleworms engineer optics - Photon02
Computer and optical communications engineers are now using optical structures to produce faster, more powerful, light-based processors and networks.

In the future, law enforcement officials may take full-colour fingerprints using new technology developed by a University of Toronto-led team of international researchers.   view more (2006-03-15)

Polymer opal films shed new kind of light on nature
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.   view more (2007-07-24)

Photonic crystal biosensors detect protein-DNA interactions
Scientists at the University of Illinois have developed a new class of disposable, microplate-based optical biosensors capable of detecting protein-DNA interactions. Based on the properties of photonic crystals, the biosensors are suitable for the rapid identification of inhibitors of... view more (2008-09-24)
