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 researchers, and thus the researches on VUV
photodetector... hiện toàn bộ
Multi-vortex laser enabling spatial and temporal encoding - 2020
Zhen Qiao, Zhenyu Wan, Guoqiang Xie, Jian Wang, Liejia Qian, Dianyuan Fan
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 active
approach for creating mul... hiện toàn bộ
Ultra-compact nonvolatile phase shifter based on electrically reprogrammable transparent phase change materials
Carlos Rı́os, Qingyang Du, Yifei Zhang, Cosmin-Constantin Popescu, Mikhail Y. Shalaginov, Paul A. Miller, Christopher Roberts, Myungkoo Kang, Kathleen Richardson, Tian Gu, Steven A. Vitale, Juejun Hu
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 state and information they
carry are ... hiện toàn bộ
All-silicon photovoltaic detectors with deep ultraviolet selectivity Tập 1 Số 1 - 2020
Yuqiang Li, Wei Zheng, Feng Huang
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 vapor deposition methods, and exhibits good performance
with repeatability... hiện toàn bộ
Promising applications of aggregation-induced emission luminogens in organic optoelectronic devices Tập 1 Số 1 - 2020
Michael Yu, Ruishan Huang, Jingjing Guo, Zujin Zhao, Ben Zhong Tang
AbstractSince the first report of aggregation-induced emission (AIE) concept in
2001, it has received intense attentions from academy and industry because of
its important applications in diverse research fronts. Up to now, the luminogens
with AIE property (AIEgens) have been widely used in optoelectronic devices,
fluorescent bioprobes and chemosensors, and researchers have also committed to
explo... hiện toàn bộ
Dual-plane coupled phase retrieval for non-prior holographic imaging
Zhengzhong Huang, Pasquale Memmolo, Pietro Ferraro
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 quantitative analysis. For
off-axis DH... hiện toàn bộ
The challenges of modern computing and new opportunities for optics
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 Law and the failure
of Dennard’s s... 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. Here, a generic
strategy based on dyn... hiện toàn bộ
