Dr. Xiang Zhang, in Air Force Office of Scientific Research-sponsored research at the University of California, Berkeley, has demonstrated the world’s smallest semiconductor laser (also known as a plasmonic laser), which may have military applications in communications, computing, and bio-hazard detection. “Proposed almost seven years ago, researchers had been unable to demonstrate a working plasmonic laser until our experiment,” said Zhang. He said this work is important because it has the potential to make plasmonic-based technologies “viable for a broad spectrum of applications.” The experiment involved using semi-conductor nanowires 1,000 times thinner than a human hair. The next phase of this research is to create an electrically operated version of the laser, which can be fully integrated with semiconductors without design modification.
