Light turns liquid
LIGHT can be turned into a glowing stream of liquid that splits into droplets and splatters off surfaces just like water. The researchers who`ve worked out how to do this say "liquid light" would be the ideal lifeblood for optical computing, where chips send light around optical "circuits" to... view more (2002-07-03)

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)

Hanover Trade Fair 2003: Precise positioning of optical fibres
Connector for the flexible set-up of optical communication networks Setting up low-cost optical communication networks requires suitable interfaces such as plug connectors or couplings which can position optical fibre ribbons with a very fine tolerance. Together with three cooperation partners, the... view more (2003-04-07)

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)

Pitt and Bell Labs researchers send 'heavy photons' over world-record distances
When light hits a semiconductor material and is absorbed, its photons can become "excitons," sometimes referred to as "heavy photons" because they carry energy, like photons, but have mass, like electrons.   view more (2005-06-22)

New hybrid microscope probes nano-electronics
A new form of scanning microscopy that simultaneously reveals physical and electronic profiles of metal nanostructures has been demonstrated at JILA, a joint institute of the National Institute of Standards and Technology (NIST) and University of Colorado at Boulder.   view more (2006-10-30)
