1Integrated lithium niobate single-mode lasers by the Vernier effect显示文摘Microcavity lasers based on erbium-doped lithium niobate on insulator(LNOI),which are key devices for LNOI integrated photonics,have attracted significant attention recently.In this study,we report the realization of a C-band single-mode laser using the Vernier effect in two coupled erbium-doped LNOI microrings with different radii under the pump of a 980-nm continuous laser.The laser,operating stably over a large range of pumping power,has a pump threshold of about 200μW and a side-mode suppression ratio exceeding 26 dB.The high-performance LNOI single-mode laser will promote the development of lithium niobate integrated photonics.Ru Zhang Chen Yang ZhenZhong Hao Di Jia Qiang Luo DaHuai Zheng HongDe Liu XuanYi Yu Feng Gao Fang Bo YongFa Kong GuoQuan Zhang JingJun Xu 2021Science China(Physics,Mechanics & Astronomy)2021,64,9:4
2Microdisk lasers on an erbium-doped lithium-niobite chip显示文摘Lithium niobate on insulator(LNOI) provides a platform for the fundamental physics investigations and practical applications of integrated photonics. However, as an indispensable building block of integrated photonics, lasers are in short supply. In this paper, erbium-doped LNOI laser in the 1550-nm band was demonstrated in microdisk cavities with high quality factors fabricated in batches by UV exposure, inductively coupled plasma reactive ion etching, and chemomechanical polishing. The threshold and conversion efficiency of the erbium-doped LNOI microdisk laser were measured to be lower than 1 m W and 6.5×10^(-5)%, respectively. This work will benefit the development of integrated photonics based on LNOI.Qiang Luo ZhenZhong Hao Chen Yang Ru Zhang DaHuai Zheng ShiGuo Liu HongDe Liu Fang Bo YongFa Kong GuoQuan Zhang JingJun Xu 2021Science China(Physics,Mechanics & Astronomy)2021,64,3:4
3Clinical evaluation of Technetium-99m sestamibi myocardial perfusion SPECT in diabetes with suspected coronary artery diseases显示文摘Objective:To study the clinical value of Technetium-99m sestamibi myocardial perfusion single photon emission computed tomography(SPECT) in diabetes with suspected coronary artery diseases.Methods:Seventy-eight diabetic patients complicated with cardiac symptoms or electrocardiogram(ECG) abnormalities and suspected coronary heart disease hospitalized in the department of endocrinology from January,2008 to December,2008 were investigated.Technetium-99m sestamibi myocardial perfusion SPECT was performed in all patients.Exercise stress test was done in 35 cases(group A).Adenosine stress test was done in 43 cases(group B).Results:The positive rates in the two groups were 54.29%(19/35) and 53.48%(23/43),respectively.There was no statistic difference between the 2 groups(P>0.05).The abnormality rates in male and female groups were 63.04% and 28.13%,respectively(P<0.01).Eighty-six segments of perfusion abnormality were detected in 38 positive patients.Four segments of fixed defect were found in 4 cases.Conclusion:As non-invasive method,myocardial perfusion SPECT can play an important role in the treatment of diabetes with suspected coronary artery disease.Deng Huixing Ma Aiqun Yang Aimin Cheng Hu Ran Hongde 2010Journal of Medical Colleges of PLA(China)2010,25,4:2

10Effect of Mo Addition on the Microstructure and Properties of TiNiNb Alloy显示文摘The influence of Mo addition on the microstructure and properties of TiNiNb alloy with 4.5 at.% Nb has been investigated systemically.The experimental results indicated that the uniform distribution of Mo depresses the appearance of coarse b-Nb particles at the grain boundaries and short stripped texture consisting of abundant fine disperse Nb-rich particles appears around the grain boundaries.The yield strength of the alloy was enhanced from 450 to 600 MPa due to the solution strengthening of Nb and Mo and the elongation reached 18% when the Mo content is 0.5 at.%.At the same time,the shape memory effect of the alloy also is improved significantly by the Mo addition.The maximum recoverable strain of the alloy with 0.5 at.% Mo is near 8% and has reached the high level of Ni–Ti binary alloys.This novel highstrength alloy is promising to be used for high pressure tube and the macro-scale coupling with higher-quality requirements.Haichang Jiang Ying Chen Dan Yang Hongding Sun Jianmin Zeng Lijian Rong 2014Acta Metallurgica Sinica(English Letters)2014,27,2:0
