Reporter learned from the Hunan University, the University Professor of Micro and Nanotechnology Research Center, headed by Zou Bing-Suo Nano Photonics Group and Arizona State University led by Cun-Zheng Ning Nano Photonics Group Cooperation Will Semiconductor Laser Chip Tuning range expansion, successfully demonstrated a 500 nm up to 700 nm red light green light, setting a new semiconductor laser tuning range of the world record, and the original maximum tuning range compared to only several tens of nanometers to achieve a major breakthrough. The results published in the latest issue of the international academic journal "Nano Letters" (NanoLetters) on.
The results of the material will be applied to the new light source, optical communication, molecular and biological sensing, solar energy Battery And so on. For example, in a new light areas, such as replacing incandescent and use the kinds of materials, light-emitting devices, issued under the same conditions, bright light is much more than now, and save energy; in optical communications, application of the results can be well improve the performance of photonic devices has greatly enhanced the performance of optical communication; in molecular and biological sensing and detection in the field, application of the results will be prepared and the original can be completely different self-luminous Sensor Parts, greatly enhance the molecular and biological sensing and detection efficiency or sensitivity; this tunable laser spectroscopy can be used to improve the current technology; In addition, this material can be applied widely around the world today is the solar Battery Area used for solar cell substrates, will greatly enhance the photoelectric conversion efficiency of solar cells.
A long time, how to improve the tuning range semiconductor lasers in order to fully play the role of the laser, has been the goal of fighting international experts; but the main factor restricting the progress that has been unable to overcome the light-emitting materials and substrate materials, the structure or the stress with the problem, resulting in material composition can not be significantly adjusted, it can not achieve a wide range of laser tuning.
General semiconductor laser tuning range up to only several tens of nanometers, restricting its application in many fields. Zou Bing-Suo nano photonics group led by another way, the growth of technology with one-dimensional nanostructures, to avoid problems with the structure of materials, components can be made adjustable to a wide range of nanowires, and Ning Cun-Zheng's photonics team work closely to achieve from green, yellow, orange and red light to the single-chip tunable laser emission, to solve this international problem.
Zou Bing-Suo-led team has been working in recent years, low-dimensional semiconductor nanostructures Photonics Research, and the first in China to carry out semiconductor nanowires and nano-lasers and other optical waveguide of research, in the multi-functional nano-structured photonic semiconductor materials, devices and theoretical study made a number of important results, is the leading domestic and international advanced level.
