| contents | As optical telecommunication networks become more complex, there is an emerging need for systems capable of very complex switching and manipulation of large numbers of optical signals. MEMS enable these systems by combining excellent capabilities and optical properties of macroscopic optomechanics with dense integration of multiple actuators on a single chip. Such optical MEMS present common design and process challenges, such as multiple electrical and optical IO, optical surface quality, optical integration density (fill factor) and actuator performance and reliability. We have used general design approaches such as pure-flexure design, electrostatic actuation and residual stress engineering in addressing these challenges. On several examples in this paper we illustrate these approaches along with underlying design tradeoffs and process requirements. We also describe specific numerical techniques useful for electrostatic actuator optimization and for analyzing the effects of residual stress. |
