Abstract: A method and apparatus for directing an optical beam, such as a laser beam used in an optical communications network. A micromirror is actuated to encounter, is mechanically latched by, a latching mechanism which holds the micromirror in position even when the actuating force is subsequently removed. The micromirror may subsequently be released to an unactuated state. The invention allows low power actuation and fixed latching without the need for additional power after switching has occured. The latching mechanism provides a fixed stop which eliminates the need for active feedback to align the switching micromirror and provides tolerance to shock and vibration in addition to the elimination of any position sensitivity.
