Pingie: HTTP:: Smallest Semiconductor Laser Created at UCB

HTTP:: Smallest Semiconductor Laser Created at UCB
--------
Ever since lasers first appeared, efforts have been oriented towards making them more efficient, smaller, larger, or more powerful. While some laser facilities boast instruments spanning hundreds of feet in size, some scientists are working on the micro- and nanoscale, to create devices with applications in handling single molecules or nanostructures. Recently, scientists at the University of California in Berkeley (UCB) have devised the smallest semiconductor laser in the world, again innovating this field of research, ScienceDaily reports. The innovation is that much more important, as the team has not only managed to shine light in such a small space, but has also been able to sustain it as it has moved along. This essentially means that it has developed a laser. “This work shatters traditional notions of laser limits, and makes a major advance toward applications in the biomedical, communications and computing fields,” UCB Nanoscale Science and Engineering Center !
Director and Professor of Mechanical Engineering Xiang Zhang explains. He is also the leader of the team behind the new laser. The work was funded by the US National Science Foundation (NSF). In a paper published in the August 30th advanced online issue of the respected scientific journal Nature, the experts describe that the new ...
