About
Dr. Junqiu Liu is a leading figure in integrated photonics and laser-based sensing, whose work has revolutionized coherent LiDAR technology. His research centers on microcombs—chip-scale frequency combs—and their application to high-speed, parallel ranging systems. Liu’s most notable contribution is the development of dual-chirped microcombs, which enable megapixel-line-rate parallel ranging, dramatically accelerating LiDAR’s speed and resolution. This breakthrough, detailed in his highly cited 2022 paper (88 citations), addresses a critical bottleneck in coherent laser ranging, which, unlike time-of-flight methods, offers immunity to ambient light and higher continuous-wave power. By harnessing microcombs, Liu has unlocked the potential for ultra-fast, dense 3D imaging, with direct implications for autonomous navigation, industrial monitoring, and atmospheric dynamics. His work bridges fundamental photonics and practical sensing, achieving significant impact with over 88 citations on this key paper alone. Liu’s achievements position him as a transformative innovator, pushing the boundaries of what chip-scale devices can achieve in real-world ranging applications.
