Red light-emitting diode sets new efficiency record

Osram Opto Semiconductors has raised the efficiency of its high-performance red light-emitting diode (LED) by 30% under laboratory conditions. This record-setting efficiency was achieved through optimization of the chips. ...

A smarter way to make ultraviolet light beams

Existing coherent ultraviolet light sources are power hungry, bulky and expensive. University of Michigan researchers have found a better way to build compact ultraviolet sources with low power consumption that could improve ...

The impending revolution of low-power quantum computers

By 2017, quantum physics will help reduce the energy consumption of our computers and cellular phones by up to a factor of 100. For research and industry, the power consumption of transistors is a key issue. The next revolution ...
