| 1 | Second harmonic generation in a high-Q lithium niobate microresonator fabricated by femtosecond laser micromachining显示文摘We report on second harmonic generation(SHG) in on-chip high-Q(>105) lithium niobate(Li Nb O3, LN) microresonators fabricated by femtosecond laser micromachining. We examine the efficiency of SHG with either a continuous-wave(CW) or an ultrashort pulsed pump laser. The normalized conversion efficiencies of SHG obtained with the CW and pulsed pump lasers are measured to be 1.35×10?5 m W?1 and 2.30×10?6 m W?1, respectively. | LIN JinTian XU YingXin FANG ZhiWei WANG Min WANG NengWen QIAO LingLing FANG Wei CHENG Ya | 2015 | Science China(Physics,Mechanics & Astronomy)2015，58，11： | 25 |
| 2 | Advances in on-chip photonic devices based on lithium niobate on insulator显示文摘Crystalline lithium niobate(LN)is an important optical material because of its broad transmission window that spans from ultraviolet to mid-infrared and its large nonlinear and electro-optic coefficients.Furthermore,the recent development and commercialization of LN-on-insulator(LNOI)technology has opened an avenue for the realization of integrated on-chip photonic devices with unprecedented performances in terms of propagation loss,optical nonlinearity,and electro-optic tunability.This review begins with a brief introduction of the history and current status of LNOI photonics.We then discuss the fabrication techniques of LNOI-based photonic structures and devices.The recent revolution in the LN photonic industry has been sparked and is still being powered by innovations of the nanofabrication technology of LNOI,which enables the production of building block structures,such as optical microresonators and waveguides of unprecedented optical qualities.The following sections present various on-chip LNOI devices categorized into nonlinear photonic and electro-optic tunable devices and photonic-integrated circuits.Some conclusions and future perspectives are provided. | JINTIAN LIN FANG BO YA CHENG JINGJUN XU | 2020 | Photonics Research2020，8，12： | 26 |

| 5 | Performance of a collector-storage solar air heating system for building mechanical ventilation preheating in the cold area显示文摘The application of solar thermal energy to preheat cold fresh air for mechanical ventilation could save a lot of energy and ensure the stable operation of the ventilation system.In this paper,a kind of collector-storage solar air heating system(CSSAHS),in which the thermal storage unit(TSU)is characterized by a dual S-channel for heat transfer,is proposed and the mathematical model for the integrated system was established.The model including the TSU,solar air collector,heat recovery device,and the fan was verified by an experimental study set up in a typical cold city in China.The model has been verified by experiments.The simulation results demonstrate that fresh air is the most important factor affecting storage/release efficiency.The increasing rate of heat release efficiency in the range of fresh air temperature-6-18°C is about 1.58%/°C.The solar heat collector area and the size of the TSU suitable for representative cities in cold regions are optimized based on multi-condition simulation analysis.The CSSAHS can preheat fresh air for 5 h after heat storage and the release efficiency is between 52 and 74%.Compared with other systems,the energy-saving rate of the CSSAHS is 26.5-33.3%in cold winter,and the heat supply ratio of the TSU is 24.4-35.1%. | Jingxuan Guan Kailiang Huang Jintian Xu Guohui Feng Jiasen Song | 2023 | Energy and Built Environment2023，4，6： | 0 |
| 6 | Co-doping strategy enhanced the ionic conductivity and excellent lithium stability of garnet-type Li_(7)La_(3)Zr_(2)O_(12)electrolyte in all solidstate lithium batteries显示文摘Garnet-type Li_(7)La_(3)Zr_(2)O_(12)(LLZO)is one of the most promising solid-state electrolytes(SSEs).However,the application of LLZO is limited by structural instability,low ionic conductivity,and poor lithium stability.To obtain a garnet-type solid electrolyte with a stable structure and high ionic conductivity,a series of TaeCe co-doping cubic Li_(6.4)La_(3)Zr_(1.4-x)Ta_(0.6)Ce_(x)O_(12)(LLZTCO,x=,0.02,0.04,0.06,0.08,0.10,0.20,0.30)electrolytes were successfully synthesized through conventional solid-phase method.The Ta^(5+)doping can introduce more lithium vacancies and effectively maintain the stability of the cubic phase.The Ce^(4+)with a larger ionic radius is introduced into the lattice to widen the Lit migration bottleneck size,which significantly increased the ionic conductivity to 1.05×10^(-3)S/cm.It also shows excellent stability to lithium metal by the optimization of Lit transport channel.Li||LLZTCO||Li symmetric cells can cycle stably for more than 6000 h at a current density of 0.1 mA/cm^(2)without any surface modifications.The commercialization potential of LLZTCO samples in all solid-state lithium batteries(ASSLBs)is confirmed by the prepared LiFePO_(4)||LLZTCO||Li cells with a capacity retention rate of 98%after 100 cycles at 0.5C.This new co-doping method presents a practical solution for the realization of high-performance ASSLBs. | Ziqiang Xu Xin Hu Bowen Fu Kashif Khan Jintian Wu Teng Li Haiping Zhou Zixuan Fang Mengqiang Wu | 2023 | Journal of Materiomics2023，9，4： | 0 |
