A dash of gold improves microlasers

Gold. The word brings to mind wedding rings, buried treasure and California in the 1840's. But when gold is reduced to 1/100,000 the size of a human hair, it takes on an entirely new personality.

Textured LED gives green light to Li-Fi

Standard light-emitting diodes (LEDs) used for home lighting can now transmit data more rapidly between electronic devices, thanks to new research from A*STAR.

New ultra-high density optical storage technology

According to current estimates, dozens of zettabytes of information will be stored electronically by 2020, which will rely on physical principles that facilitate the use of single atoms or molecules as basic memory cells. ...

The quantum sniffer dog

As humans, we sniff out different scents and aromas using chemical receptors in our noses. In technological gas detection, however, there are a whole host of other methods available. One such method is to use infrared lasers, ...

Silicon nanoparticles trained to juggle light

A team of physicists from ITMO University (Saint Petersburg) and Moscow Institute of Physics and Technology (MIPT) has demonstrated the potential of silicon nanoparticles for effective non-linear light manipulation. Their ...
