    Abstract: The invention provides a fiber-optic 2×2 switch using a dual-fiber 50:50 input coupler and a dual-fiber 50:50 output coupler. One fiber from each coupler makes contact to an inner transparent electrode on a planar layer of electro-optic material and the other fibers make contact to an outer transparent electrode on the layer. The electro-optic layer has its other side coated with a transparent electrode which is placed in optical contact with one end of a GRIN lens. The fibers are arranged so that the inner fibers are at conjugate points and the outer fibers also at conjugate points of the lens. The other end of the lens is coated with a mirror. Applying a voltage between either the inner or outer electrode changes the optical path length for the light from and to the fibers traveling through the material under the selected electrode causing the light from the two input fibers to be switched between the two output fibers. 2×N switches can be constructed by concatenating 2×2 switches. The switch can also be used as a modulator. A convenient fiber alignment method is described.

    Abstract translation: 本发明提供一种使用双光纤50:50输入耦合器和双光纤50:50输出耦合器的光纤2x2开关。 来自每个耦合器的一根光纤与电光材料的平面层上的内部透明电极接触，并且其它光纤与层上的外部透明电极接触。 电光层的另一侧涂有透明电极，该透明电极与GRIN透镜的一端放置成光学接触。 纤维布置成使得内纤维在共轭点处，外纤维也在透镜的共轭点处。 透镜的另一端涂有镜子。 在内部电极或外部电极之间施加电压改变来自穿过选定电极之下的材料的光的光路长度，从而使来自两个输入光纤的光在两个输出光纤之间切换。 2xN开关可以通过连接2x2开关构成。 开关也可以用作调制器。 描述了方便的光纤对准方法。

    Abstract: The present disclosure provides a displacement amplification structure and a method for controlling displacement. In one aspect, the displacement amplification structure of the present disclosure includes a first beam and a second beam substantially parallel to the first beam, an end of the first beam coupled to a fixture site, and an end of the second beam coupled to a motion actuator; and a motion shutter coupled to an opposing end of the first and second beams. In response to a displacement of the motion actuator along an axis direction of the second beam, the motion shutter displaces a distance along a transversal direction substantially perpendicular to the axis direction.

    Abstract: A system includes receiving information regarding a first keyword associated with a user, where the first keyword is usable by a content distribution system to select content for distribution based on keywords associated with the user. The system also includes obtaining an attribute associated with the user; identifying at least one keyword category corresponding to the attribute; and selecting at least one alternative keyword associated with the at least one identified keyword category. The selecting may include consulting a taxonomy database to identify alternative keywords that are relevant to the first keyword. The system also includes ranking the at least one alternative keyword according to a ranking rule associated with the at least one keyword category associated with the at least one alternative keyword; and providing information associated with the ranked at least one alternative keyword to the user for selection by the user.

    Abstract: A MEMS variable optical attenuator (VOA) chip includes a frame having a planar surface, a micro-electric actuator with a movable optical shutter arranged with respect to the planar surface of the frame, where the VOA is actuated by thermal expansion. The micro-electric actuator comprises semiconductor conductors (“wires”) that can be moved, upon applying an electrical current, by thermal expansion. In one embodiment, the MEMS VOA chip is configured in a multiple wire arrangement that restricts the shutter movement in a plane.
