ABSTRACT:
A micro-optical device having an aligned waveguide switch. The device includes a stationary input part, a stationary output part and a movable part. The stationary input part and the stationary output part each have a plurality of input and output waveguides, respectively. The movable part has a plurality of switching waveguides and is movable relative to the stationary input and output parts. A stop block limits movement of the movable part in order to align at least one of the switching waveguides with the applicable input waveguide(s) and output waveguide(s). The movement of the movable part is substantially transverse.
