| 1 | Light-Induced Photorefractive Waveguides in Iron-Doped Lithium Niobate Crystals显示文摘Waveguides were fabricated in lithium niobate crystals solely by light irradiation using binary optical masks and SLM-prepared optical masks. Arrayed-waveguides were also obtained by once or twice irradiations of an interferogram of two plane waves. | Jianlin Zhao Peng Zhang Dexing Yang Bili Li(Department of Applied Physics, Northwestern Polytechnical University, Xi’an 710072, P.

| 6 | Freestanding metal nanohole array for high-performance applications显示文摘Plasmonic devices using periodic metallic nanostructures have recently gained tremendous interest for color filters,sensing,surface enhanced spectroscopy,and enhanced photoluminescence,etc.However,the performance of such plasmonic devices is severely hampered by the solid substrates supporting the metallic nanostructures.Here,a strategy for freestanding metallic nanomembranes is introduced by taking advantages of hollow substrate structures.Large-area and highly uniform gold nanomembranes with nanohole array are fabricated via a flexible and simple replication-releasing method.The hollow structures include a hollow core fiber with 30μm core diameter and two ferrules with their hole diameter as 125 and 500μm,respectively.As a proof-of-concept demonstration,2 times higher sensitivity of the bulk refractive index is obtained with this platform compared to that of a counterpart on a solid silica substrate.Such a portable and compact configuration provides unique opportunities to explore the intrinsic properties of the metal nanomembranes and paves a new way to fabricate high-performance plasmonic devices for biomolecule sensing and color filter. | Bobo Du Yinlan Ruan Dexing Yang Peipei Jia Shoufei Gao Yingying Wang Pu Wang Heike Ebendorff-Heidepriem | 2020 | Photonics Research2020，8，11： | 0 |
| 7 | Influence of parameters on light propagation dynamics in optically induced planar waveguide arrays显示文摘The diffraction and refraction of light beam in optical periodic structures can be determined by the photonic band-gap structures of spatial frequency.In this paper,by employing the equation governing the nonlinear light propagations in photorefractive crystals,we study the photonic band-gap structures, Bloch modes,and light transmission properties of optically induced planar waveguide arrays.The relationship between the photonic band-gap structures and the light diffraction characteristics is discussed in detail.Then the influence of the parameters of planar waveguide arrays on the band-gaps structures,Bloch modes,and linear light transmissions is analyzed.It is revealed that the linear light transmission properties of waveguide arrays are tightly related to the diffraction relationships determined by band-gap structures.And the Bloch modes corresponding to different transmission bands can be excited by different excitation schemes.Both the increases of the intensity and the period of the array writing beam will lead to the broadening of the forbidden gaps and the concentration of the energy of the Bloch modes to the high-index regions.Furthermore,the broadening of the forbidden gaps will lead to separation and transition between the Bloch modes of neighboring bands around the Bragg angle.Additionally,with the increase of the intensity of the array writing beams,the influences from light intensity will tend to be steady due to the saturation of the photorefractive effect. | LIU Sheng ZHANG Peng XIAO FaJun YANG DeXing ZHAO JianLin | 2009 | Science China(Physics,Mechanics & Astronomy)2009，52，5： | 0 |
| 8 | Solvent-free partial oxidation of cyclohexane to KA oil over hydrotalcitederived Cu-MgAlO mixed metal oxides显示文摘A highly efficient and stable hydrotalcite-derived Cu-MgAlO catalyst was developed for the partial oxidation of cyclohexane with molecular oxygen.The physical–chemical properties of Cu-MgAlO catalysts were studied,and the results indicated that the copper component had been successfully introduced into the hydrotalcite unit layer structure.The catalytic reaction results showed that copper as the active species could activate CAH bond and effectively promote the decomposition of cyclohexyl hydroperoxide(CHHP)to the mixture of cyclohexanol and cyclohexanone(KA oil).8.3%of cyclohexane conversion and 82.9%of selectivity for KA oil were obtained over 9%Cu-MgAlO catalyst at 150℃with 0.6 MPa of oxygen pressure for 2 h.Especially,its catalytic performance was still stable after five runs. | Jian Jian Dexing Yang Peng Liu Kuiyi You Weijie Sun Hu Zhou Zhengqiu Yuan Qiuhong Ai Hean Luo | 2022 | Chinese Journal of Chemical Engineering2022，35，2： | 0 |
