Chinese researchers from Nankai University and City University of Hong Kong have made a groundbreaking advancement in millimeter-wave radar technology with their new thin-film lithium niobate (TFLN) photonic radar chip. Published in Nature Photonics, this innovation is poised to transform a variety of cutting-edge applications, including 6G communication, autonomous driving, and precision sensing.
The integration of advanced photonic technologies with millimeter-wave radar systems enables unprecedented high-resolution imaging and detection capabilities. This is particularly essential for applications that require rapid and precise sensing. The new chip, built on a 4-inch TFLN platform, leverages a material renowned for its exceptional ability to manipulate light and electrical signals. Its compatibility with CMOS processes, the technology behind most modern electronics, ensures that it can be produced at scale.
What sets this chip apart is its ability to achieve centimeter-level resolution in both distance and velocity detection. Utilizing inverse synthetic aperture radar (ISAR), the chip excels in two-dimensional imaging, allowing it to create detailed images of objects even in challenging environments.
\"This chip represents a significant leap forward in radar technology. It not only overcomes the limitations of traditional electronic radar systems but also sets a new standard for compact, high-performance photonic radar systems,\" said Zhu Sha, professor and key member of the research team from Nankai University.
