Vacuum-ultraviolet photodetectors - 2020
Lemin Jia, Wei Zheng, Feng Huang
Abstract
High-performance vacuum-ultraviolet (VUV) photodetectors are of great significance to space science, radiation monitoring, electronic industry and basic science. Due to the absolute advantages in VUV selective response and radiation resistance, ultra-wide bandgap semiconductors such as diamond, BN and AlN attract wide interest from researcher...... hiện toàn bộ Multi-vortex laser enabling spatial and temporal encoding - 2020

AbstractOptical vortex is a promising candidate for capacity scaling in next-generation optical communications. The generation of multi-vortex beams is of great importance for vortex-based optical communications. Traditional approaches for generating multi-vortex beams are passive, unscalable and cumbersome. Here, we propose and demonstrate a multi-vortex laser, an...... hiện toàn bộ Ultra-compact nonvolatile phase shifter based on electrically reprogrammable transparent phase change materials

AbstractOptical phase shifters constitute the fundamental building blocks that enable programmable photonic integrated circuits (PICs)—the cornerstone of on-chip classical and quantum optical technologies [1, 2]. Thus far, carrier modulation and thermo-optical effect are the chosen phenomena for ultrafast and low-loss phase shifters, respectively; however, the stat...... hiện toàn bộ All-silicon photovoltaic detectors with deep ultraviolet selectivity Tập 1 Số 1 - 2020

AbstractFor a practical photodetector, fast switching speed and high on-off ratio are essential, and more importantly, the integration capability of the device finally determines its application level. In this work, the judiciously engineered Si3N4/Si detector with an open-circuit voltage of 0.41 V is fabricated by chemical...... hiện toàn bộ Promising applications of aggregation-induced emission luminogens in organic optoelectronic devices Tập 1 Số 1 - 2020

AbstractAccurate depiction of waves in temporal and spatial is essential to the investigation of interactions between physical objects and waves. Digital holography (DH) can perform quantitative analysis of wave–matter interactions. Full detector-bandwidth reconstruction can be realized based on in-line DH. But the overlapping of twin images strongly prevents quant...... hiện toàn bộ Metamaterial anapole plasmon học cho cảm biến chỉ số khúc xạ Dịch bởi AI

Chong Li, Xiang Zhang, Jingwei Li, Tao Fang, Xiaowen Dong
AbstractIn recent years, the explosive development of artificial intelligence implementing by artificial neural networks (ANNs) creates inconceivable demands for computing hardware. However, conventional computing hardware based on electronic transistor and von Neumann architecture cannot satisfy such an inconceivable demand due to the unsustainability of Moore’s L...... hiện toàn bộ Metasurface with dynamic chiral meta-atoms for spin multiplexing hologram and low observable reflection - 2022
He Wang, Zhe Qin, Lingling Huang, Yongfeng Li, Ruizhe Zhao, Hongqiang Zhou, Haoyang He, Jieqiu Zhang, Shaobo Qu
AbstractSpin light manipulation based on chiral metasurfaces is a striking hotspot that has intrigued huge attention. Circular dichroism, a unique phenomenon of chiral atoms/molecules, has been regarded as another auxiliary dimension for guiding electromagnetic waves, which has been explored in the field of artificial material sciences yet a challenging issue.
