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.   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 electronic structure and the ferromagnetic properties of Cu(mal)(DMF) (n)(mal = malonate dianion, DMF = N,N-dimethylformamide) 期刊论文  OAI收割 Journal of Magnetism and Magnetic Materials, 2008, 卷号: 320, 期号: 3-4, 页码: 458-462 K.
