Terahertz radiation, which lies between the infrared and microwave ranges, has unique properties such as the ability to penetrate materials without damaging them, making it a valuable tool for non-destructive testing and spectroscopy, said Vladimir Pavelyev, head of the nanoengineering department at Samara University.
The developed elements will find application in materials processing, creation of optoelectronic devices and telecommunications. Pavelev also noted that they will make it possible to replace point-to-point scanning with focusing on specific areas, which will increase the efficiency of scanning systems.
The work was carried out at special facilities, including the Novosibirsk Free Electron Laser (NFEL) at the Institute of Nuclear Physics SB RAS. In the future, scientists plan to create photonic elements for longer wavelengths.
