ABSTRACT:
An optical routing apparatus that allows flexible and effective routing of optical signals between input and output ports is provided. The apparatus makes use of one or more linearly actuated mirrors, with different routing configurations of the optical signals resulting from different mirror positions. For each such mirror, the linear actuation is may be performed along an axis that is either parallel or perpendicular to the mirror surface.
