Berkeley Study Provides Unprecedented Details on Ultrafast Processes in Diamond Nitrogen Vacancy Centers

From supersensitive detections of magnetic fields to quantum information processing, the key to a number of highly promising advanced technologies may lie in one of the most common defects in diamonds. Researchers at the Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California (UC) Berkeley have taken an important step towards unlocking this key with the first ever detailed look at critical ultrafast processes in these diamond defects.

*Berkeley Lab Researchers Find Simpler Approach to Making Plasmonic Materials*

The question of how many polyhedral nanocrystals of silver can be packed into millimeter-sized supercrystals may not be burning on many lips but the answer holds importance for one of today’s hottest new high-tech fields – plasmonics! Researchers with the U.S. Department of Energy (DOE)’s Lawrence Berkeley National Laboratory (Berkeley Lab) may have opened the door to a simpler approach for the fabrication of plasmonic materials by inducing polyhedral-shaped silver nanocrystals to self-assemble into three-dimensional supercrystals of the highest possible density.

*IBM Silicon Nanophotonics uses optical signals to connect chips together faster and with lower power*

Yorktown Heights, N.Y. – 01 Dec 2010: IBM scientists today unveiled a new chip technology that integrates electrical and optical devices on the same piece of silicon, enabling computer chips to communicate using pulses of light (instead of electrical signals), resulting in smaller, faster and more power-efficient chips than is possible with conventional technologies.

The new technology, called CMOS Integrated Silicon Nanophotonics, is the result of a decade of development at IBM’s global Research laboratories. The patented technology will change and improve the way computer chips communicate – by integrating optical devices and functions directly onto a silicon chip, enabling over 10X improvement in integration density than is feasible with current manufacturing techniques.
