Researchers Modify "Cornell Dots" to Make the World's Tiniest Laser

Researchers have modified nanoparticles known as "Cornell dots" to make the world's tiniest laser -- so small it could be incorporated into microchips to serve as a light source for photonic circuits. The device may also have applications for sensors, solar collectors and in biomedicine.

Critical Component for Possible Future Technologies Based on Nanophotonic Circuitry

Because the new device, called a "spaser," is the first of its kind to emit visible light, it represents a critical component for possible future technologies based on "nanophotonic" circuitry, said Vladimir Shalaev, the Robert and Anne Burnett Professor of Electrical and Computer Engineering at Purdue University.

Nanotechnology Research Revolutionizing How Computers Work

The London Centre for Nanotechnology (LCN) - a joint venture between UCL and Imperial College London - is leading two international projects to develop radically new approaches to miniaturising computer systems, which would require less energy and make data storage completely stable, among other benefits.

Work is a Further Advance in the Study of Metamaterials

While the researchers can't promise delivery to a parallel universe or a school for wizards, books like Pullman's Dark Materials and JK Rowling's Harry Potter are steps closer to reality now that researchers in China have created the first tunable electromagnetic gateway.

New Centre Training Next Generation of Experts in Photonics

A new centre for doctoral training at UCL is preparing to train the next generation of experts in the growing science of photonics. Just as electronics uses electrons to perform different functions, photonics combines electronics with the control of photons - elementary 'packages' of light - to perform similar or more advanced functions.

Ytterbium Giving Time Standards Community More Options in Development of Next-Generation Atomic Clocks

An experimental atomic clock based on ytterbium atoms is about four times more accurate than it was several years ago, giving it a precision comparable to that of the NIST-F1 cesium fountain clock, the nation’s civilian time standard, scientists at the National Institute of Standards and Technology (NIST) report in Physical Review Letters.*
