Optical 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.
A 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.
Texas Instruments has announced that its complete logic portfolio is now offered in Pb-free solutions for all finishes and balls.
MIT researchers have combined organic materials with high-performing inorganic nanocrystals to create a hybrid optoelectronic structure
Technical Insights Frost & Sullivan has discovered two developments in the light-emitting diode (LED) arena. A single LED, with the facility to switch its emission spectrum and a hybrid device based on an inorganic quantum dot/organic LED combination capable of enhanced luminescence.
Texas 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.
Macronix, Taiwan has announced an agreement with Mitsubishi Electric which covers 0.15 um DINOR Flash technology development, joint design of product and wafer manufacturing.
Agilent has introduced high speed optocouplers, claimed to be capable of transmitting data at a 50 megabaud (MBd) rate, allowing high speed collection and control in industrial automation applications where isolation is required.
The future of nanoelectronics looks promising. Built with nanotubes and various self-assembling molecular structures, this technology may revolutionise the elctronic world by replacing the silicon transistor in approximately ten years.
German company, Cairos Technologies is developing an automated soccer refereeing technology that could result in fewer disagreements over decisions particularly the offside rule.
