Abstract
The present invention provides an optical switch. The switch includes a substrate and a first waveguide holding member. The switch also includes a second waveguide holding member disposed over the substrate and movable relative to the first waveguide holding member to provide a switching function. A movement guiding member is provided for guiding the movement of the second waveguide holding member. A registration element is disposed at the movement guiding member for positioning the second waveguide holding member at a selected location relative to the first waveguide holding member. The selected location is one that provides alignment between a selected waveguide of the first waveguide holding member and a selected waveguide of the second waveguide holding member.
