The interconnection characteristics of these two types of rearrangeable nonblocking EBN were studied  optical insertion loss of 4.6 dB  and the logic program for driving switching units was provided. The calculated insertion loss was 3.3 dB for 88 optical matrix switch. Silica waveguide 88 matrix optical switch was designed and fabricated according to the calculated results. The silica waveguide propagation loss of 0.1 dB/cm and waveguide-fiber coupling loss of 0.5dB/point were measured. With the fabricated 87times  cross-talk of -38 dB  polarization dependent loss of 0.4 dB  averaged switching power of 1.6 W  and switching time of 1 ms were achieved. A basic agreement between experimental results and theoretical calculated values was achieved.   Geometry parameter optimization of large cross-sectional S-shaped bent rib waveguides for silicon based optical switches 期刊论文  OAI收割 chinese physics letters, 2007, 卷号: 24, 期号: 3, 页码: 744-746 Li ZY (Li Zhi-Yong); Liu JW (Liu Jing-Wei); Yu JZ (Yu Jin-Zhong) 收藏  |  浏览/下载：110/0  |  提交时间：2010/03/29 摘要: By using a genetic algorithm  geometry parameters of large cross-sectional S-bend rib waveguides are optimized aiming at the least total loss when the propagation loss is considered. 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.
