| 1 | Optical meta-waveguides for integrated photonics and beyond显示文摘The growing maturity of nanofabrication has ushered massive sophisticated optical structures available on a photonic chip.The integration of subwavelength-structured metasurfaces and metamaterials on the canonical building block of optical waveguides is gradually reshaping the landscape of photonic integrated circuits,giving rise to numerous metawaveguides with unprecedented strength in controlling guided electromagnetic waves.Here,we review recent advances in meta-structured waveguides that synergize various functional subwavelength photonic architectures with diverse waveguide platforms,such as dielectric or plasmonic waveguides and optical fibers.Foundational results and representative applications are comprehensively summarized.Brief physical models with explicit design tutorials,either physical intuition-based design methods or computer algorithms-based inverse designs,are cataloged as well.We highlight how meta-optics can infuse new degrees of freedom to waveguide-based devices and systems,by enhancing light-matter interaction strength to drastically boost device performance,or offering a versatile designer media for manipulating light in nanoscale to enable novel functionalities.We further discuss current challenges and outline emerging opportunities of this vibrant field for various applications in photonic integrated circuits,biomedical sensing,artificial intelligence and beyond. | Yuan Meng Yizhen Chen Longhui Lu Yimin Ding Andrea Cusano Jonathan A.Fan Qiaomu Hu Kaiyuan Wang Zhenwei Xie Zhoutian Liu Yuanmu Yang Qiang Liu Mali Gong Qirong Xiao Shulin Sun Minming Zhang Xiaocong Yuan Xingjie Ni | 2021 | Light(Science & Applications)2021，10，12： | 6 |
| 2 | Microscopic and Fractal Characterization of Organic Matter within Lacustrine Shale Reservoirs in the First Member of Cretaceous Qingshankou Formation,Songliao Basin,Northeast China显示文摘Understanding the occurrences of different fractions of organic matter in shale reservoirs is very important for the evaluation of shale oil.Lacustrine organic-rich shale samples from the first member of the Cretaceous Qingshankou Formation in the Songliao Basin were analyzed with confocal laser scanning microscopy(CLSM)and fluorescence spectral analysis.The results show that the occurrences of different organic components are related to the fabric of samples and vary with depth.The bulk content of light components is significantly higher than heavy components and exhibits a positive relationship with quartz and feldspar contents.Both light and heavy components are distributed parallel with the lamination in microscopic view in laminated samples,and randomly in massive samples.The maximum radius of light components in most of the samples is larger than 20μm,while it is smaller for heavy components,indicating the micro fractionation from clay/organic lamina to quartz/feldspar lamina.The depth of enrichment of light components corresponds to the oil maturity of organic matter.Both the distribution of light and heavy components fits the same fractal model,with fractal dimensions ranging between 2.2 and 2.5.The CLSM results confirm that it can be a reliable tool for the'sweet spot'exploration. | Bo Liu Meng Yan Xianda Sun Yunfeng Bai Longhui Bai Xiaofei Fu | 2020 | Journal of Earth Science2020，31，6： | 2 |

| 4 | Phase-controlled van der Waals growth of wafer-scale 2D MoTe_(2) layers for integrated high-sensitivity broadband infrared photodetection显示文摘Being capable of sensing broadband infrared(IR)light is vitally important for wide-ranging applications from fundamental science to industrial purposes.Two-dimensional(2D)topological semimetals are being extensively explored for broadband IR detection due to their gapless electronic structure and the linear energy dispersion relation.However,the low charge separation efficiency,high noise level,and on-chip integration difficulty of these semimetals significantly hinder their further technological applications.Here,we demonstrate a facile thermal-assisted tellurization route for the van der Waals(vdW)growth of wafer-scale phase-controlled 2D MoTe_(2)layers.Importantly,the type-ⅡWeyl semimetal 1T'-MoTe_(2)features a unique orthorhombic lattice structure with a broken inversion symmetry,which ensures efficient carrier transportation and thus reduces the carrier recombination.This characteristic is a key merit for the well-designed 1T'-MoTe_(2)/Si vertical Schottky junction photodetector to achieve excellent performance with an ultrabroadband detection range of up to 10.6μm and a large room temperature specific detectivity of over 108 Jones in the mid-infrared(MIR)range.Moreover,the large-area synthesis of 2D MoTe_(2)layers enables the demonstration of high-resolution uncooled MIR imaging capability by using an integrated device array.This work provides a new approach to assembling uncooled IR photodetectors based on 2D materials. | Di Wu Chenguang Guo Longhui Zeng Xiaoyan Ren Zhifeng Shi Long Wen Qin Chen Meng Zhang Xin Jian Li Chong-Xin Shan Jiansheng Jie | 2023 | Light(Science & Applications)2023，12，1： | 0 |
