Abstract

We have designed and fabricated a micromirror array using single crystalline silicon (SCS) for data communication applications. The mirror array has $16{\times}16$ micromirrors and each mirror has $120{\mu}m{\times}100{\mu}m$ reflective surface. Electrostatic force was adopted as a driving mechanism. The spring dimensions were determined using relationship between spring dimensions and driving voltage. The designed tilting angle was $9.6^{\circ}$, and measured tilting angle according to applied voltages were experimented. The response time was measured using He-Ne laser and position sensitive diode (PSD), and lifetime was checked for reliability proof.
