Shifting sound to light may lead to better computer chips
.. the last decade, pioneering experiments using sub-picosecond lasers have demonstrated the generation and detection of acoustic and shock waves in materials with terahertz (THz) frequencies. These very same experiments led to a new technique fo more

Exploring the Ultimate Nanoscale for Future Electronics
..a laser pulse and convert the solid to a plasma plume that is deposited on the substrate," Martin explains. "We choose the substrate structure and control the temperature and atmosphere to get the right mix and the right phase." more

Tiny disk-shaped lasers as small as a speck of dust could one day beam information through optical computers. Unfortunately, a perfect disk will spray light out, not as a beam, but in all directions. New theoretical results, reported in the Optical Society (OSA) journal Optics Letters, explain how adding a small notch to the disk edge provides a single outlet for laser light to stream out. more
Princeton researchers discover new type of laser
..searchers has discovered an entirely new mechanism for making common electronic materials emit laser beams. The finding could lead to lasers that operate more efficiently and at higher temperatures than existing devices. "This discovery p more
A quantum halfway house between the magnet and semiconductor
..milar effects in devices made using materials and methods found in laser pointers. This would put what we've seen firmly in the realm of that which can easily be achieved using current technologies." The first author of the paper, Dr. N more
Soliton Waves Could Lead to All-Optical Telecoms Switches
..y soliton lasers (CSL), both as continuous waves and as pulsed waves that can be switched on and off. They worked from the premise that since a soliton in an optical fibre is self-sustaining once it has been created, a cavity soliton is similarl more
