The 18 wavelength-selective switch (WSS) based on micro electro mechanical systems (MEMS) technology is proposed and fabricated with micro electromagnetic actuators  8 WXC prototype node is implemented by using 18 WSSs as building elements. The working principle and the configuration of the micro electromagnetic actuator are illuminated. By analysis  reflecting prisms and narrow-band thin films filters. And a 8  the property suits for the application when the inputs are 2V  and the best fiber-to-fiber insertion loss 5dB is gotten.   A novel bottom-emitting vcsel's one-dimension array (EI CONFERENCE) 会议论文  OAI收割 Optoelectronic Materials and Devices III, October 27, 2008 - October 30, 2008, Hangzhou, China 作者:  Wang L.;  Wang L.;  Wang L.;  Liu Y.;  Liu Y. 收藏  |  浏览/下载：17/0  |  提交时间：2013/03/25 A novel 980nm bottom-emitting VCSELs array with high power density and good beam property of Gaussian far-field distribution is reported. This array is composed of 5 symmetrically-arranged elements of 200m  150m and 100m-diameter  with the center spacings of 300m and 250m respectively. The maximum power is 880mW at a current of 4A  corresponding to lKW/cm2 average optical power density. The differential resistance is 0.09 with a threshold of 0.56A. The novel array is compared with a 300m-aperture-size single device and a 44 2-D array with 50m element aperture size and 250m centre spacing. The three devices have the same lasing area. The conclusion is that the novel array is better in the property of output power  threshold current  lasing spectra  far-field distribution etc. 2008 SPIE.   Proposal and investigation for a planar MOEMS 1x8 wavelength-selective switch - art. no. 683608 会议论文  OAI收割 2008 作者:  Li W.;  Li W. 收藏  |  浏览/下载：4/0  |  提交时间：2013/03/28 Characteristics of ZnMgO-based metal-semiconductor-metal photodetectors (EI CONFERENCE) 会议论文  OAI收割 International Symposium on Photoelectronic Detection and Imaging, ISPDI 2007: Photoelectronic Imaging and Detection, September 9, 2007 - September 12, 2007, Beijing, China 作者:  Zhang J.;  Li B.;  Li B.;  Li B.;  Zhao Y. 收藏  |  浏览/下载：18/0  |  提交时间：2013/03/25 In recent years  ZnMgO semiconductor alloys  with a direct bandgap tunable between 3.37 eV and 7.8 eV  become one of the most suitable materials for the fabrication of ultraviolet detectors. In this paper  we have fabricated metal-semiconductor-metal photodetectors on 1-m thick Zn 0.8Mg0.2O films. The interdigital metal electrodes are 500 m long and 5 m wide with an interelectrode spacing 2 m  5 m and 10 m  respectively. Zn0.8Mg0.2O films were grown on quartz by ratio frequency magnetron sputtering at 500C. Dark current  spectral responsivity and pulse response were carried out for the devices with different finger pitches. All the photodetectors showed the peak responsivity at 330 nm and the ultraviolet-visible rejection ratio (R330 nm/R400 nm) is more than four orders of magnitude at 3 V bias. For the device with 2 m finger pitch  the detectivity was calculated as 4.21011 cm Hz 1/2/W at 330 nm. Furthermore  the transient response measurement for all devices revealed similar rise time of 10 ns. The 90%-10% fall times are 130 ns  170 ns and 230 ns for the devices with different finger pitches of 2 m  5 m and 10 m  respectively..   Central hole effect on Whispering-Gallery-Mode of triangular lattice photonic crystal microcavity (EI CONFERENCE) 会议论文  OAI收割 Optoelectronic Materials and Devices III, October 27, 2008 - October 30, 2008, Hangzhou, China 作者:  Zhang Y.;  Wang L.;  Wang L.;  Wang L.;  Wang Z. 收藏  |  浏览/下载：15/0  |  提交时间：2013/03/25 Whispering-Gallery-Mode (WGM) photonic crystal microcavity is a kind of photonic crystal application and can potentially be used for miniaturized photonic devices  such as thresholdless lasers. In this paper we study the WGM of photonic crystal microcavities focusing on the so called H2 cavities which are formed by removing seven air holes. The WGM in these large-size cavities has some advantages compared with single defect WGM in the view of real device applications. We further add a central air hole in the cavity region to analyze the effect on WGM in the microcavity by finite difference time domain (FDTD) and plane wave expansion (PWE). It is found that the tolerance of WGM is large enough for the fabrication of electrical injection structure. 2008 SPIE.   The cosmic-ray energy spectrum around. the knee measured by the Tibet-III air-shower array 会议论文  OAI收割 14th International Symposium on Very High Energy Cosmic Ray Interactions, Weihai, PEOPLES R CHINA, 2001 作者:  Amenomori, M.;  Ayabe, S.;  Bi, X.
