摘要：One-by-three and two-by-two optical switches comprising optical waveguides or fibers with tapered ends that utilize electrostatically- driven actuators are disclod. Tapering of the fiber ends allow the ends to be positioned in clo proximity to one another to yield an optical switch with low inrtion loss. In one embodiment the optical switch compris: (1) four optical waveguides each having a tapered end comprising two tapered edges and dispod on a support such that each tapered edge of each waveguide is in oppod and near-abutting relation with a tapered edge of another optical waveguide, said near abutment defining a space between each pair of oppos tapered edges; (2) a first electromechanical actuator operable to move at least a first optical device into and out of a path of an optical signal travelling between two of the waveguides, wherein the first optical device moves in the space between a first pair of oppod tapered edges; and (3) a cond electromechanical actuator operable to move at least a cond optical device into and out of the path of the optical signal, wherein the cond optical device moves in the space between a cond pair of oppod tapered edges, wherein one tapered edge of the first pair and one tapered edge of the cond
pair are common to one of the optical waveguides.
