Because the spectral signals in the ionosphere distributing basically in the far-ultraviolet waveband are very weak. Usual spectrometer structures and detectors such as CCD can't receive enough information. Based on this principle of atmospheric sounding  the imaging spectrometer prototype for ionosphere detection application was designed to solve the problem. This prototype consists of the telescope and the imaging spectrometer. The simple structure and small number of mirrors can help higher transmission efficiency be achieved and weak signals detection be implemented. The telescope is an off-axis parabolic mirror and the spectrometer is a modified Czerny-Turner spectral imaging system. Modified Czerny-Turner spectrometer contains a spherical mirror  a fixed plane grating and a toroidal mirror. By adjusting the incident angle to the collimating mirror and using toroidal mirror  coma and astigmatism were corrected well. We also optimize distances between the grating to the focusing mirror and the focusing mirror to the image plane to improve disadvantages of traditional Czerny-Turner structure. Designed results demonstrate that aberrations are substantially corrected  and high image quality can be obtained in broad waveband. The photon counting Wedge-Strip-Anode detector with micro-channel planes as the receiving plane is accepted for the instrument prototype. The other photon counting 2-D detector responding well for weak light such as Cross-Delay line detector and MAMA detector can also be used for detection. The calibration and performances testing system is made of a vacuum system  a deuterium lamp  a monochrometer and the instrument prototype. Results obtained from the experiment show that the spectral resolution is 2.4 nm and the spatial resolution is 80 m. The other calibration experiments are running. The technology of the spectrometer prototype is important for the research and applications of ionosphere remote sensing. 2011 SPIE.   Effects of GaN Capping on the Structural and the Optical Properties of InN Nanostructures Grown by Using MOCVD 期刊论文  OAI收割 journal of the korean physical society, 2010, 卷号: 57, 期号: 1, 页码: 128-132 Sun YP (Sun Yuanping); Sun Y (Sun Yuanping); Cho YH (Cho Yong-Hoon); Wang H (Wang Hui); Wang LL (Wang Lili); Zhang SM (Zhang Shuming); Yang H (Yang Hui) 收藏  |  浏览/下载：523/2  |  提交时间：2010/08/17 InN  Burstein-Moss effect  Quantum confinement effect  Activation energy  FUNDAMENTAL-BAND GAP  WELL STRUCTURES  EMISSION  SINGLE   The effect of an electric field on the nonlinear response of InAs/GaAs quantum dots 期刊论文  OAI收割 journal of optics, JOURNAL OF OPTICS, 2010, 2010, 卷号: 12, 12, 期号: 5, 页码: art. no. 055203, Art.

In order to see the effect the change of the quantum well structure on the characteristic temperatures  different structures were attempted. For the 808 nm structure  we tried different barrier thicknesses. For the 810 nm structure  different cavity lengths were attempted. And we studied the 940 nm and 980 nm also. In this paper  the widths of these devices were all 100 m. Characteristic temperatures of these devices were calculated. The appropriate structure was available for different application. 2008 SPIE.   High-power electroabsorption modulator for radio over fibre system 期刊论文  OAI收割 journal of physics d-applied physics, 2007, 卷号: 40, 期号: 14, 页码: 4120-4122 作者:  Pan JQ 收藏  |  浏览/下载：44/0  |  提交时间：2010/03/29 QUANTUM WELL STRUCTURES   Correlation between optical and electrical properties in In0.52Al0.48As/InxGa1-xAs metamorphic high-electron-mobility-transistor structures on GaAs substrates 期刊论文  OAI收割 journal of applied physics, 2006, 卷号: 100, 期号: 3, 页码: art.no.033705 Cui LJ (Cui L.
