Duk-Yong Choi

Associate Professor Duk-Yong Choi is a faculty member at the Australian National University (ANU) in the Department of Quantum Science and Technology. He leads the Laser Physics, Optics, and Photonics research group, focusing on advanced photonic technologies.

His research spans:

• Integrated Photonics: Design of chip-based devices for microwave signal processing, Brillouin scattering, and nonlinear applications.
• Metasurfaces & Nanophotonics: Development of dielectric metasurfaces for beam shaping, sensing, encryption, and optical trapping.
• Chalcogenide Glass: Exploitation of nonlinear properties for supercontinuum generation, mid-IR sensing, and low-loss waveguides.
• Quantum & Nonlinear Optics: High-harmonic generation, entangled photon sources, and ultrafast optical processing.

Recent publications emphasize metasurface innovation (e.g., vector beams, Poincaré beams), integrated mid-IR systems for gas sensing, and Brillouin-based RF photonics. No awards or advised students are listed in the source.
