Yong Liu

Yong Liu is a Researcher at the Department of Electrical and Photonics Engineering, Technical University of Denmark (DTU), specializing in integrated photonics for optical beam steering and LiDAR systems. He actively supervises PhD projects and maintains a robust publication record in photonics research.

His research spans Phased Array Engineering, Optics, and Photonics, with core interests in beam steering mechanics, silicon photonic integrated circuits, and optical communication systems. Recent work focuses on ultra-sparse phased arrays and soliton-based comb generation in microresonators.

Liu's 2024-2025 publications reveal a concentrated effort to advance solid-state beam steering through novel silicon photonics designs, particularly for LiDAR applications, while bridging fundamental optical physics with real-world sensing technologies.

He supervises key DTU projects:

• Integrated 1D Optical Phased Array for Solid-state Beam Steering (2024-2027)
• Integrated 2D Optical Phased Array for Solid-State Beam Steering (2024-2027)

funded through institutional grants targeting photonic integrated circuit development.

Liu operates within DTU Fotonik's Photonic Integrated Circuit based Systems group, a collaborative hub advancing photonic circuit technologies for communication and sensing applications.
