A fiber optic connector may include a body, at least one input coupling configured to receive at least one fiber optic input cable, at least one output coupling configured to receive at least one fiber optic output cable, and at least one shuttle. The shuttle may be movable within the body between a connected position and a disconnected position, wherein the at least one fiber optic input cable and the at least one fiber optic output cable are optically connected when the at least one shuttle is in the connected position, and wherein the at least one fiber optic input cable and the at least one fiber optic output cable are not optically connected when the at least one shuttle is in the disconnected position.

Mechanisms and designs of large scale, modular, robotic software-defined patch-panels incorporate numerous features that ensure reliable operation. A telescopic arm assembly (104) with actuated gripper mechanism (103) is used to transport internally latching connectors (101) within a stacked array of translatable rows (102). A unique two-state magnetic latching feature provides reliable, low loss optical connections. Flexible, magnetically levitated internal structures are provided to assist the robot in automatically aligning to, engaging, and disengaging any internal connection in a fast reliable process within the stacked array.

MEMS resonators containing a first material and a second material to tailor the resonator's temperature coefficient of frequency (TCF). The first material has a different Young's modulus temperature coefficient than the second material. In one embodiment, the first material has a negative Young's modulus temperature coefficient and the second material has a positive Young's modulus temperature coefficient. In one such embodiment, the first material is a semiconductor and the second material is a dielectric. In a further embodiment, the quantity and location of the second material in the resonator is tailored to meet the resonator TCF specifications for a particular application. In an embodiment, the second material is isolated to a region of the resonator proximate to a point of maximum stress within the resonator. In a particular embodiment, the resonator includes a first material with a trench containing the second material.

摘要:
An optical switch device (1) of such a type that the coupled state of light guides is switched by moving a light reflective member capable of securely preventing a movable body with the light reflective member from being displaced and allowing a reduction in thickness, comprising a pressing member (41) switching the movable body (2) with a prism mirror (10) mounted thereon between a clamped state and an unclamped state, a twisted spring (60) energizing the pressing member in a clamping direction, and a magnetic drive circuit (45) for clamping driving the pressing member (41) in the unclamped state against the torsion spring (60). The magnetic drive circuit (45) for clamping further comprises a clamp coil (72) on the fixed member (13) side and clamp magnets (70, 71) on the pressing member (41) side. The clamp magnets (70, 71) are disposed so as to hold the clamp coil (72) from the inside and outside of the opening thereof with the different poles thereof opposed to each other.
