Method of manufacture of a micromechanical optical switch

Provided with improved the MEMS-based the optical switch (100), and method for manufacturing such the optical switch. According to one embodiment, an optical switch comprises a to displace Beam Jiegou (124) close (122) is composed of a driving unit of (104) and a driving unit coupling lens (102). The lens, a whole between the wave guide slot (106) extends and position is one end of the wave guide the shrinking to move. The driving unit flow force is a Beam of Jiegou position or shrinking positions of a movable to displace and mirror, and is a to exert force, A Jiegou the lens a to the position of the position or shrinking position.
