From an article in Physics by Technical University of Valencia.
The Semiconductor Institute (CAS) of the Chinese Academy of Sciences, China’s Beijing University of Posts and Telecommunications (BUPT), the Air Force Early Warning Academy (Wuhan, China) and the University of Ottawa (Canada) have also participated with the Photonics Research Labs-iTEAM of the Universitat Politècnica de València (UPV) participates in its development.
In the study published in the journal Nature Communications, the team of researchers from Spain, China, and Canada presents a time-symmetry concept called parity-time (PT) symmetry, which is applied to frequency-swept systems. Their proposal makes it possible to reduce the linewidth of the generated waves by up to 14 times, thus obtaining more stable and precise signals than those obtained with conventional systems.
One of the areas where this technology can have an immediate impact is autonomous transport. “LiDAR systems are essential for navigation and obstacle detection in these vehicles. With our technology, by increasing their precision, they will be able to identify and respond to their environment more quickly and accurately, which would contribute to their development and implementation on a global scale,” says José Capmany, director of UPV’s Photonics Research Labs-iTEAM and co-author of the study.
In addition, the technology developed by the team from the UPV, BUPT, the CAS Institute, the Air Force Early Warning Academy and the University of Ottawa will also improve environmental surveillance and monitoring.
