On the morning of February 28th, Beijing time, a group of scientists led by chemist John Badding of Pennsylvania State University in the United States developed a fiber with zinc selenide as the core material, which can be used as a light yellow compound for semiconductors. This new type of optical fiber can operate light more efficiently and freely, which will lay the foundation for more applications of lidar technology. This technology can further improve medical laser surgery and provide the military with more advanced lasers for measuring and detecting pollutants and detecting the spread of terrorist chemical drugs. The research results of the scientists have been published in Advanced Materials, the top journal of materials science. Badding said: "We all know that optical fiber is the cornerstone of development in the modern information age. The newly developed long and thin optical fiber is only as thin as three human hairs, but it can transmit terabytes of data per second, which is equivalent to 250. The information burned on the DVD. And, there are still various ways to improve this technology. " Badding explained that the existing optical fiber technology is always limited to the glass material, he said: "The atomic arrangement of glass is accidental, and the new material is contrary to it. The zinc selenide crystal material is highly ordered, this kind of Ordering is very conducive to the transmission of light in long waves, especially in the mid-infrared. " Badding said: "Different from quartz glass traditionally used for optical fiber, zinc selenide is a compound semiconductor. We have always known that zinc selenide is a useful compound that can perform a variety of operations on light. This is quartz glass. It cannot be done. The special thing is to make zinc selenide into a fiber structure, which has never been done before. " Scientists have discovered that optical fibers synthesized from zinc selenide have two major uses. First, they found that the new optical fibers are more efficient in color conversion. Badding explained: "Traditional optical fibers are used for signal, display, and art, but they cannot To ensure that the desired color is always available, zinc selenide uses non-linear frequency conversion and has a very good ability to change color. " Secondly, scientists have discovered that the new optical fiber not only provides more functional applications in the visible spectrum, but also in the infrared, and the wavelength of electromagnetic radiation is longer than visible light.
