​On May 23, the Chinese Journal of Lasers released China's Top 10 Optical Breakthroughs During 2021. One of them was a polarization-insensitive broadband achromatic metalens based on titanium dioxide for near-IR biological imaging, developed by the team of Prof. Xiao Shumin from HITSZ's School of Materials Science and Engineering. This offers the possibility of replacing traditional lenses wit...

We experimentally demonstrate the perovskite vortex microlasers with highly directional outputs and well-controlled topological charges. Lead halide perovskite microlasers have been very promising for versatile optoelectronic applications. However, most perovskite microlasers are linearly polarized with uniform wavefront. The structured laser beams carrying orbital angular momentum have rarely...

On July 10, the 2020 Guangdong-Hong Kong-Macao University Alliance Online Annual Conference and Principal Forum was held in the form of a video conference. President of Harbin Institute of Technology and President of Harbin Institute of Technology (Shenzhen) Zhou Yu attended the meeting and delivered a speech. Assistant President of Harbin Institute of Technology (Shenzhen) Wei Jun attended the...

AbstractThe achievement of structural color has shown advantages in large-gamut, high-saturation, high-brightness, and high-resolution. While a large number of plasmonic/dielectric nanostructures have been developed for structural color, the previous approaches fail to match all the above criterion simultaneously. Herein we utilize the Si metasurface to demonstrate an all-in-one solution for st...

"Congratulations on your successful defense!" On March 18, after more than two hours of defense, Gu Jiahui, a 2016 doctoral candidate from the school of materials science and engineering, completed the online defense of his graduation thesis at his home in Weihai, Shandong Province, becoming the first doctoral student to taste the "cloud defense" in Harbin Institute of Technology (Shenzhen)."I ...
