Abstract | We report a novel single-crystal-silicon (SCS)-based micromirror that can perform large bi-directional scans and can also generate large piston motion. The micromirror rotates over ±15° at less than 6 V dc voltage, and over ±43° (i.e., >170° optical scan angle) at its resonance of 2.4 kHz. A maximum vertical piston motion of 200 μm is also achieved with this 700 μm-by-320 μm device. A circuit model has been developed for electrothermal behavioral simulation and design optimization. The simulation results using the circuit model match the experimental data to within 8%. |
