Analytical formulae for the squeeze film damping coefficient and the squeeze film damping moment on the cantilever beam of the optical switch are derived. Based on the torsion dynamics theory  the technique and relative results are presented for analyzing the actuating voltage and the switch time. The optimized result of parameters is as: length  width and thickness of the torsion beam are 700  12 and 10 m  length and width of the cantilever beam are 1900 and 1000 m  length and width of the balance beam are 100 and 1000 m  shortest spacing between the upper and lower electrodes is 0.05 m  and highness of the lower electrode is 55 m  respectively. The actuating voltage is less than 10 V  and the switching time of Ton and Toff are 1.30ms and 1.25ms  respectively. The computed results show that the air squeeze film damping is an important factor for the study of dynamic response on MOEMS optical switch.   Study on optical parts of MOEMS optical switch with low insertion loss (EI CONFERENCE) 会议论文  OAI收割 MEMS/MOEMS Technologies and Applications II, November 10, 2004 - November 12, 2004, Beijing, China 作者:  Wang W.;  Wang L.;  Wang L.;  Wang L.;  Chen W. 收藏  |  浏览/下载：32/0  |  提交时间：2013/03/25 We study insertion losses of optical switch when the laser beam is propagating during the free space between two single mode fibers (SMFs) and the related assemblage challenges  Then a new packaging structure is developed for the hybrid-integration of free-space MOEMS (micro-opto-electro-mechanical systems) chip with a silicon micromachined submount to improve alignment accuracy. The submount is designed to accommodate various free-space MOEMS chips with minimal active optical alignment  thus reducing the packaging cost. The silicon submount has a central recess to place the MOEMS chip in  sixteen V-grooves for optical fibers  and micropits for micro ball lenses  all bulk micromachined at the same time by a single anisotropic wet etching step. A corner compensation technique is employed to prevent erosion of the convex corners  where different geometries meet. Through this assembling method  the fiber  micro ball lens can be aligned preciously thus reduced lateral and angular misalignment between them. Then total insertion losses can be decreased.
