Recently, the reporter learned from Hunan University that the nanophotonics group led by Professor Zou Bingsuo of the University's Micro-Nano Technology Research Center cooperated with the nanophotonics group led by Ning Cunzhen, a professor at Arizona State University, to expand the scope of semiconductor laser chip tuning and demonstrate successfully. A 500-nanometer green light up to 700 nanometers of red light has set a new world record for the tuning range of semiconductor lasers, achieving a major breakthrough compared to the original tuning range of only a few tens of nanometers. The results paper was published in the latest international academic journal NanoLetters.
The material of this achievement will be applied to new light sources, optical communications, molecular and biosensing, solar cells and other fields. For example, in the field of new light sources, such as the replacement of incandescent lamps and the use of light-emitting devices of such materials, the light emitted under the same conditions will be much brighter than now, and energy saving; in the field of optical communication, the application of the results is very good Improve the performance of photonic components and greatly improve the performance of optical communication; in the field of molecular and biosensing and detection, the application of this result will be able to produce completely different sensor components that can emit light autonomously, greatly improving molecular and biosensing The efficiency or sensitivity of the detection; this tunable laser can also be used to improve current spectroscopy; in addition, this material can be applied to the field of solar cells that are being widely promoted around the world, and used as a substrate for solar cells. Greatly improve the photoelectric conversion efficiency of solar cells.
For a long time, how to improve the tuning range of semiconductor lasers to fully play the role of laser has always been the goal of domestic and foreign experts; but the main factor restricting this progress is that it has been unable to overcome the structural or stress coordination problems of luminescent materials and substrate materials. As a result, the material composition cannot be greatly adjusted, so that a wide range of tuning of the laser cannot be achieved.
The general semiconductor laser tuning range is only a few tens of nanometers, which limits its application in many fields. Zou Bingsuo's nanophotonics team has taken a different approach and adopted one-dimensional nanostructure growth technology to avoid structural coordination problems in materials. Nanowires with a wide range of composition adjustments can be made, working closely with Ning Cunzhen's photonics team to achieve The tunable laser emission from a single chip from green, yellow, orange to red solves this international problem.
The team led by Zou Bingsuo has been working on low-dimensional semiconductor nanostructure photonics research in recent years, and is the first in China to conduct research on semiconductor nanowire optical waveguides and nanolasers, in the research of multifunctional semiconductor nanostructure photonic materials, devices and theory. The company has achieved a number of important achievements and is at the leading level in the country and at the international advanced level.
