Abstract:
An optical switch, comprising:a plurality of input optical fibers for carrying a plurality of input optical signals; a plurality of output optical fibers; an optical switch mechanism for selectively coupling the input optical signals to selected output optical fibers, the optical switch including a substrate and a plurality of micro-mirrors on the substrate, wherein at least one of the micro-mirrors is pivotable relative to the substrate about a first axis and about a second axis perpendicular to the first axis; a first plurality of electrodes underlying the at least one micro-mirror; and a second plurality of electrodes substantially surrounding the first plurality of electrodes, wherein each of the second plurality of electrodes has an elongated sidewall portion that extends in a first direction substantially orthogonal to the first and second axes and a height in the first direction greater than a height of the first plurality of electrodes.
