The application of metalenses for multifunctional imaging
Tunable optical devices based on metasurfaces are revolutionising functional planar optics. Metalenses, flat lenses that use nanoscale phase modulation, offer compact, multifunctional solutions. In this talk, I will present my work on metalenses and metasurfaces for multifunctional imaging, from switchable bifocal and tri-channel metalenses for bright-field and edge-enhanced imaging, to spiral metalens integrated systems for ultra-fast velocity measurements. The development of these multifunctional metalens platforms paves the way for the integration into lightweight cameras, advanced sensors, and AR/VR displays.

Speaker: Dr Trevon Badloe
Trevon Badloe is an Assistant Professor in the Department of Electronics and Information Engineering at Korea University. He completed his Master’s in Physics [MPhys. Hons.] at The University of Sheffield (2012) and his Ph.D. in Mechanical Engineering at Pohang University of Science and Technology (POSTECH), South Korea (2023), supervised by Prof. Junsuk Rho. Following his Ph.D., he spent a year and a half as a PIURI postdoctoral fellow in the Graduate School of Artificial Intelligence at POSTECH (2023–2024) before joining Korea University. His current research interest is the convergence of AI and metaphotonics for multifunctional imaging and sensing, with applications in quantum optics. He has published over 90 peer-reviewed articles in prestigious international journals, including eLight, Light: Science & Applications, Advanced Materials, ACS Nano, and Advanced Photonics.
Tunable optical devices based on metasurfaces are revolutionising functional planar optics. Metalenses, flat lenses that use nanoscale phase modulation, offer compact, multifunctional solutions for imaging, displays, and augmented reality. Beyond standard imaging, metalenses enable advanced wavefront manipulation for polarisation, phase, and depth imaging, by simply tailoring the phase profile of the metalens.
