A group of scientists led by chemist John Badding of the University of Pennsylvania at the United States have developed an optical fiber made of zinc selenide as a core material that can be used as a light yellow compound for semiconductors.
This new type of optical fiber can perform more efficient and free operation of light, and will lay the foundation for more applications of laser radar technology. This technology can further improve medical laser surgery, provide the military with more advanced lasers, measure pollutants, and detect the spread of terrorism chemical drugs. The results of the scientists have been published in the Advanced Materials Science Journal.
Badding said: "We all know that optical fiber is the cornerstone of the development of modern information age. The newly developed long and thin optical fiber has only three human hairs so thin, but it can transfer terabytes of data per second, which is equivalent to 250. Information recorded on the DVD. Also, there are still various ways to improve this technology."
Badding explained that the existing optical fiber technology is always limited by the glass material. He said: "The atomic arrangement of glass is accidental, while the new material is contrary to it. The zinc selenide crystal material is highly ordered. Orderliness is very favorable for the transmission of light in long waves, especially in the mid-infrared."
Badding said: "Silicone glass is traditionally used in optical fibers. Zinc selenide is a compound semiconductor. We have always known that zinc selenide is a useful compound that can perform various operations on light. This is quartz glass. What can't be done. The special thing is to make zinc selenide into a fiber structure, which has never been done before.â€
Scientists have discovered that optical fibers made of zinc selenide have two major uses. First they discovered that new fibers are more efficient at color conversion. Basding explained: “Traditional fibers are used for signal, display, and art, but they cannot Ensure that the desired color is always available. Zinc selenide utilizes non-linear frequency conversion and is very capable of changing color.â€
Second, scientists have discovered that the new fiber not only provides more functional applications in the visible spectrum, but also in infrared light, where wavelengths of electromagnetic radiation are longer than visible light.
