In (Sulfridge, et al., 2001) we presented an actuation scheme for toggling a bistable MEMS from one stable state to the other using the radiation pressure of light. The experiments on radiation pressure revealed some unexpected behavior of the beam when toggled by short duration laser pulses. While long duration laser pulses reliably toggled the beam every time, short duration pulses only seemed to toggle the beam about half of the time. This paper presents a new, nonlinear dynamic analysis of the bistable beam device used in those experiments that explains this anomalous behavior.
