| 1 | Mid-infrared chalcogenide microfiber knot resonators显示文摘A novel type of mid-IR microresonator,the chalcogenide glass(ChG)microfiber knot resonator(MKR),is demonstrated,showing easy fabrication,fiber-compatible features,resonance tunability,and high robustness.ChG micro fibers with typical diameters around 3μm are taper-drawn from As2S3 glass fibers and assembled into MKRs in liquid without surface damage.The measured Q factor of a typical 824μm diameter ChG MKR is about 2.84×104 at the wavelength of 4469.14 nm.The free spectral range(FSR)of the MKR can be tuned from2.0 nm(28.4 GHz)to 9.6 nm(135.9 GHz)by tightening the knot structure in liquid.Benefitting from the high thermal expansion coefficient of As2S3 glass,the MKR exhibits a thermal tuning rate of 110 pm·℃^-1 at the resonance peak.When embedded in polymethyl methacrylate(PMMA)film,a 551μm diameter MKR retains a Q factor of 1.1×10^4.The ChG MKRs demonstrated here are highly promising for resonator-based optical technologies and applications in the mid-IR spectral range. | YU XIE DAWEI CAI HAO WU JING PAN NING ZHOU CHENGUANG XIN SHAOLIANG YU PAN WANG XIAOSHUN JIANG JIANRONG QIU XIN GUO LIMIN TONG | 2020 | Photonics Research2020，8，4： | 3 |

| 9 | Real-time,in situ probing of gamma radiation damage with packaged integrated photonic chips显示文摘Integrated photonics is poised to become a mainstream solution for high-speed data communications and sensing in harsh radiation environments,such as outer space,high-energy physics facilities,nuclear power plants,and test fusion reactors.Understanding the impact of radiation damage in optical materials and devices is thus a prerequisite to building radiation-hard photonic systems for these applications.In this paper,we report real-time,in situ analysis of radiation damage in integrated photonic devices.The devices,integrated with an optical fiber array package and a baseline-correction temperature sensor,can be remotely interrogated while exposed to ionizing radiation over a long period without compromising their structural and optical integrity.We also introduce a method to deconvolve the radiation damage responses from different constituent materials in a device.The approach was implemented to quantify gamma radiation damage and post-radiation relaxation behavior of SiO2-cladded SiC photonic devices.Our findings suggest that densification induced by Compton scattering displacement defects is the primary mechanism for the observed index change in SiC.Additionally,post-radiation relaxation in amorphous SiC does not restore the original pre-irradiated structural state of the material.Our results further point to the potential of realizing radiation-hard photonic device designs taking advantage of the opposite signs of radiation-induced index changes in SiC and SiO2. | QINGYANG DU JEROME MICHON BINGZHAO LI DEREK KITA DANHAO MA HAIJIE ZUO SHAOLIANG YU TIAN GU ANURADHA AGARWAL MO LI JUEJUN HU | 2020 | Photonics Research2020，8，2： | 1 |
| 10 | Experimental measurement of the quantum geometric tensor using coupled qubits in diamond显示文摘Geometry and topology are fundamental concep ts,which underlie a wide range of fascinating physical phenomena such as topological states of matter and topological defects.In quantum mechanics,the geometry of quantum states is fully captured by the quantum geometric tensor.Using a qubit formed by an NV center in diamond;we perform the first experimental measurement of the complete quantum geometric tensor.Our approach builds on a strong connection between coherent Rabi oscillations upon parametric modulations and the quantum geometry of the underlying states.We then apply our method to a system of two interacting qubits,by exploiting the coupling between the NV center spin and a neighboring13 C nuclear spin.Our results establish coherent dynamical'responses as a versatile probe for quantum geometry,and they pave the way for the detection of novel topological phenomena in solid state. | Min Yu Pengcheng Yang Musang Gong Qingyun Cao Qiuyu Lu Haibin Liu Shaoliang Zhang Martin B.Plenio Fedor Jelezko Tomoki Ozawa Nathan Goldman Jianming Cai | 2020 | National Science Review2020，7，2： | 0 |
| 11 | Effect of Metformin on Lactate Metabolism in Normal Hepatocytes under High Glucose Stress in Vitro显示文摘Objective To study the effect of metformin on lactate metabolism in hepatocytes in vitro under high glucose stress.In vitro LO2 cells,liver cells were randomly divided into blank control group,25 tendency/L glucose solution,27 tendency/L glucose solution,29 tendency/L glucose solution,31 tendency/L glucose solution,33 tendency/L glucose solution,35 tendency/L glucose solution treatment group,the optimal concentation of 31 tendency after L,use 30 tendency for L metformin solution,and then divided into blank control group,the optimal concentration of glucose solution,normal liver cells+metformin solution normal liver cells.The optimal concentration of glucose solution normal liver cells+metformin solution respectively in the 12h,24 h,48 h on cell count plate to calculate the mumber of liver cells,and using lactic acid determination kit the optimal concentration of glucose solution+normal liver cells and normal liver cells+the optimal concentration of glucose solution+metformin solution respectively in the 12 h,24 h,48 h of cell cultures of lactic acid value.There was no significant change in the lactic acid concentration but significant increase in the number of suviving hepatocytes in the high-glycemic control group compared with that in the high-glycemic control group without metformin.Metformin has no significant effect on lactic acid metabolism of hepatocytes under high glucose stess in vito,and has a protective effect on hepatocytes under high glucose stress.Based on this,it is preliminanily believed that metformin is not the direct factor leading to diabetic lactic acidosis. | Xinxin Zhou Xinliang Liu Ling Zhang Yongyan Chen Shaoliang Guo Yiying Yu Zhilu Li Pingping Yan | 2021 | Journal of Endocrinology Research2021，3，1： | 0 |
| 12 | Ultra-high extinction ratio optical pulse generation with a thin film lithium niobate modulator for distributed acoustic sensing显示文摘We experimentally demonstrate ultra-high extinction ratio(ER)optical pulse modulation with an electro-optical modulator(EOM)on thin film lithium niobate(TFLN)and its application for fiber optic distributed acoustic sensing(DAS).An interface carrier effect leading to a relaxation-tail response of TFLN EOM is discovered,which can be well addressed by a small compensation component following the main driving signal.An ultrahigh ER>50 dB is achieved by canceling out the tailed response during pulse modulation using the EOM based on a cascaded Mach–Zehnder interferometer(MZI)structure.The modulated optical_(√)pulses are then utilized as a probe light for a DAS system,showing a sensitivity up to-62.9 dB·rad∕Hz~2(7 pε/Hz)for 2-km single-mode sensing fiber.Spatial crosstalk suppression of 24.9 dB along the fiber is also obtained when the ER is improved from 20 dB to 50 dB,clearly revealing its importance to the sensing performance. | YUAN SHEN XIAOQIAN SHU LINGMEI MA SHAOLIANG YU GENGXIN CHEN LIU LIU RENYOU GE BIGENG CHEN YUNJIANG RAO | 2024 | Photonics Research2024，12，1： | 0 |
