*Abstract

This micromirror is designed for precise positioning and eliminates the need for feedback control. Unlike comparable devices, this device does not suffer from typical alignment and sensitivity problems. Moreover, a fiber-optic crossbar switch with very low insertion loss can be constructed from this mechanism.
