| American and Chinese scientists jointly developed the world's smallest semiconductor laser |
| The United States, scientists jointly developed the world’s smallest semiconductor laser. The study is called "surface plasmon laser technology" called a milestone in laser physics at August 30 in "Nature" magazine, published by the University of California at Berkeley professor of Chinese research team, led by Xiang Zhang, Peking University Professor Darren together to complete their doctoral Maren Min.
Two years ago, Zhang’s research team began working with Professor Dai Lun, Darren and other developed using CdS nanowires, the nanowire thousand times thinner than a human hair. Zhang Xiang and silver metallic nanowires separated by just insulating gap of five nanometers deep subwavelength between the two lasing in this twenty times smaller than the wavelength of space vacuum exit, since the laser mass storage in the non-narrow the gap in the metal, which greatly reduces the possibility of the loss of light.
And had a cloak technology developed by the United States included in "Time" magazine in 2008 the top ten scientific discoveries of Professor Zhang Xiang visit the 31st accept the news agency said the results of this study to break the traditional concept of laser limits, the first human to be able to gather light hair millionth achieve laser emission range, the first to achieve a surface plasmon laser technology, this size is only about the size of a single protein molecule, which is very close to the electron wavelength, photons and electrons in the future be able to truly interact.
The technology of human will and what impact? Zhang Xiang said the technology is not only a major breakthrough in basic science research, but also for biomedical applications such as communications and computer science will also have a profound impact. "In terms of biomedical scientists can detect DNA and cancer at the molecular size. While the communications and computer technology, can help achieve a higher density optical or magnetic information storage."
Thus, we can be confident that in the near future, a single disc can store books in a library.
Zhang Xiang at Nanjing University completed a bachelor’s and a master’s degree in 1996 from the University of California, Berkeley, Ph.D., respectively, at Pennsylvania State University, University of California at Los Angeles, in 2004 returned to Berkeley, Ernster S·Kur is currently Professor, also served as director of the U.S. national Center for Nanoscale Science and Engineering. He led the research team in August last year developed a stealth materials technology, the human system to do real stealth cloak dream possible. | | |  |
