Postgraduate training

News:

2024.09

Yuqing Cheng and his collaborators at Peking University have realized a wideband, high resolution ratio, integrated circular-polarized photodetector by using a chiral resolved near-field mode in an achiral structure. The results were published in Light: Science & Applications on September 27, 2024. Yuqing Cheng and Guowei Lyu are co-corresponding authors, and doctoral student Guanyu Zhang is the first author.
