Abstract:
1. A micro-optical device having an aligned waveguide switch, comprising: a semiconductor substrate; a stationary input part arranged on the semiconductor substrate, the stationary input part having a plurality of channels, and each channel being an input waveguide; a stationary output part arranged on the semiconductor substrate, the stationary output part having a plurality of channels, and each channel being an output waveguide; a movable part movably arranged on the semiconductor substrate, the movable part having a plurality of channels, and each channel being a switching waveguide, the movable part being movable relative to the stationary input and output parts; at least one stop block that limits movement of the movable part to align at least one of the switching waveguides with at least one of the input waveguides and at least one of the output waveguides, wherein movement of the movable part is substantially transverse; and at least one bumper connected to the movable part, the bumper bumping into the stop block in order to stop the movable parts, wherein an insulating layer is arranged between the semiconductor substrate and the stationary input part, the stationary output part and the movable part.
