| 1 | Inverse design and realization of an optical cavity-based displacement transducer with arbitrary responses显示文摘Optical cavity has long been critical for a variety of applications ranging from precise measurement to spectral analysis.A number of theories and methods have been successful in describing the optical response of a stratified optical cavity,while the inverse problem,especially the inverse design of a displacement sensitive cavity,remains a significant challenge due to the cost of computation and comprehensive performance requirements.This paper reports a novel inverse design methodology combining the characteristic matrix method,mixed-discrete variables optimization algorithm,and Monte Carlo method-based tolerance analysis.The material characteristics are indexed to enable the mixed-discrete variables optimization,which yields considerable speed and efficiency improvements.This method allows arbitrary response adjustment with technical feasibility and gives a glimpse into the analytical characterization of the optical response.Two entirely different light-displacement responses,including an asymmetric sawtooth-like response and a highly symmetric response,are dug out and experimentally achieved,which fully confirms the validity of the method.The compact Fabry-Perot cavities have a good balance between performance and feasibility,making them promising candidates for displacement transducers.More importantly,the proposed inverse design paves the way for a universal design of optical cavities,or even nanophotonic devices. | Qianbo Lu Qingxiong Xiao Chengxiu Liu Yinan Wang Qixuan Zhu Manzhang Xu Xuewen Wang Xiaoxu Wang Wei Huang | 2023 | Opto-Electronic Advances2023，6，3： | 0 |
| 2 | Focus on perovskite emitters in blue light-emitting diodes显示文摘Blue perovskite light-emitting diodes(PeLEDs)are essential in pixels of perovskite displays,while their progress lags far behind their red and green counterparts.Here,we focus on recent advances of blue PeLEDs and systematically review the noteworthy strategies,which are categorized into compositional engineering,dimensional control,and size confinement,on optimizing microstructures,energy landscapes,and charge behaviors of wide-bandgap perovskite emitters(bandgap>2.5 eV).Moreover,the stability of perovskite blue emitters and related devices is discussed.In the end,we propose a technical roadmap for the fabrication of state-of-the-art blue PeLEDs to chase and achieve comparable performance with the other two primary-color devices. | Xiaoyu Yang Li Ma Maotao Yu Hao-Hsin Chen Yongqiang Ji An Hu Qixuan Zhong Xiaohan Jia Yanju Wang Yuzhuo Zhang Rui Zhu Xinqiang Wang Changjun Lu | 2023 | Light(Science & Applications)2023，12，8： | 0 |
