Paper Abstract

Torsion micro-mirror is the key structure of MEMS optical devices such as MEMS optical switches, MEMS variable optical attenuator, MEMS scanning micro-mirror array and so on. In this paper, after testing a silicon-based non-silicon micro-mirror fabricated by bulk micromachining, some important measurement data has been achieved. It is clear that this silicon-based non-silicon micro-mirror scheme can has just less than 15 degree rotation at 20V driving voltage while the beam thickness is just 0.5 m m . In order to improving the stability, reliability and optical properties of the micro-mirror, a new scheme has been put forward and the fabricating process using surface-micromachining has been simulated. It is shown that the new scheme will improve the characteristics of the micro-mirror effectively.
