Abstract

We propose to develop a MEMS-based optical shutter system with transition times faster than 10 microseconds and attenuations of at least 70 dB. The device will be designed for wavelengths between 780 and 894 nm, as needed for laser systems for cold-atom microsystems. Specific design features and techniques will be incorporated to trap and prevent the passage of stray light through the system.
