Tunable optical fibres
04 March, 2003Optical fibres regularly carry billions of phone conversations and other data transmissions every day and are a fundamental part of optical sensing and numerous medical applications. The photonic devices responsible for this traffic are being made even more efficient and versatile by handing over some of the switching and reconfiguring chores to the fibres themselves - the trunk lines linking all the optical nodes.
Molecular Switch
24 February, 2003A molecular switch took only 47 zepto-joules to operate in a recent experiment, 10,000 times less than transistor switches used in current high-speed computers. The molecular switch consists of rotating one of the four phenyl legs attached to a complicated porphyrin molecule from one stable position to another.

Chip made on 90 nm process
29 January, 2003Texas Instruments' fully functional wireless digital base band on 90 nm process offers many benefits. By shrinking the dimension of the transistors power consumption, size and manufacturing costs are reduced relative to the previous manufacturing process. Distances between transistors are also reduced, increasing overall processor performance and allowing integration of many more features on an equivalent size chip.
