Abstract:
In this work, we present the study of the transient behaviors of the bi-stable mechanism used for a MEMS optical switch. The major part of the bi-stable mechanism consists of two constrained curved structures (the double-curved beam). As the applied force exceeds a critical value, the double-curved beam snap-through to the other stable state. We use the finite element method (FEM) to simulate both the static and transient snap-through behaviors of the bi-stable mechanism. Also, the simulated results will be compared with the measured results to study the influence of post-snap-through dynamics on the optical performance of the optical switch.
