Abstract
An optical switch ( ) includes a cover ( ), a base ( ), two input ports ( ), two output ports ( ), a movable reflecting element ( ), a fixed reflecting element ( ), and a driving means ( ). The movable reflecting element has a first mirror ( ) and an opposite facing second mirror ( ). The fixed reflecting element has a third mirror ( ). The movable reflecting element is movable by the driving means from a first position, in which signals transmit from input to output ports without reflection from mirrors, to a second position, in which reflection from the mirrors effects a switching of the optical signals to different output ports. The presence of the fixed reflecting element automatically compensates for a distance between the first and second mirrors, allowing reflected signals to accurately align with respective output ports.
