Optimized results are presented as an example of S-bend rib waveguides based on silicon-on-insulator (SOI) 4 x 4 optical switches. The value of 2dB/cm is given to the propagation loss according to the experimental results. The simulation results indicate that the total loss drops from 1.0002dB down to 0.4375dB without considering a lateral offset. If the offset is adopted  the total loss reduces from 0.5463dB to 0.2365dB. In addition  the effect of the rib height ratio on the loss is analysed  and the optimal ratio is obtained to be 0.55.   Energy band design for Si/SiGe quantum cascade laser 期刊论文 acta physica sinica, 2007, 卷号: 56, 期号: 7, 页码: 4137-4142 Lin GJ (Gui-Jiang, Lin); Zhou ZW (Zhou Zhi-Wen); Lai HK (Lai Hong-Kai); Li C (Li Cheng); Chen SY (Chen Song-Yan); Yu JZ (Yu Jin-Zhong) 收藏  |  浏览/下载：30/0  |  提交时间：2010/03/29 SiGe material   Status and trends of short pulse generation using mode-locked lasers based on advanced quantum-dot active media 期刊论文 journal of physics d-applied physics, 2007, 卷号: 40, 期号: 18, 页码: r307-r318 作者:  Xu B 收藏  |  浏览/下载：33/0  |  提交时间：2010/03/29 1.3 MU-M   Research on the influence of fabrication parameters on the performance of buried ion-exchanged glass waveguides using the variational method 期刊论文 optical and quantum electronics, 2007, 卷号: 39, 期号: 15, 页码: 1289-1296 Zhang, YL; Zhu, NH; Wen, JM; Pun, EYB; Chung, PS 收藏  |  浏览/下载：68/10  |  提交时间：2010/03/08 erbium-ytterbium co-doped glass waveguides  ion-exchanged  trial solution  variational method   Layout Design and Optimization of RF Spiral Inductors on Silicon Substrate 期刊论文 半导体学报, 2006, 卷号: 27, 期号: 5, 页码: 769-773 作者:  Xue Chunlai 收藏  |  浏览/下载：14/0  |  提交时间：2010/11/23
