| 摘要 |
The present invention is related to a novel micro-electro-mechanical systems (MEMS) torsional drive that is capable of tilting suspended structure such as a micro-mirror for steering light beams in three-dimensional analog fashion, which is suitable for high port count optical switches. The torsional drive has the advantages of allowing large tilt angle, having low drive voltage, and capable of providing a feedback signal for closed-loop control.
