摘要： A variable optical delay line using MEMS devices. A reflector on a micro machine linear rack is positioned and spaced from an input source and/or an output to receive and reflect input light waves toward the output. The distance between the reflector and the input and output is variable and thereby enables selective path delay compensation of the input light wave signals. Other disclosed embodiments utilize pivoting MEMS mirrors and selective adjustment of the mirror pivot angles to provide the selective path delay compensation required in a light wave system.

摘要： A micro-machined transducer having a structure in which an acoustic enclosure is formed on a substrate above the plane of the substrate surface is disclosed. Forming the acoustic enclosure on the substrate above the plane of the substrate surface, rather than an acoustic cavity in a surface of the substrate, provides an acoustic cavity whose size is not limited by the thickness of the substrate.

摘要： A moving mirror switch includes a focusing element adapted to focus an incoming light beam transmitted from an input optical port, a movable mirror, and an actuator. The actuator moves the mirror between first and second mirror positions corresponding to reflective and pass-through states, respectively. In the reflective state, the mirror at least partially reflects the focused beam back upon the input port. In the pass-through state, the focused beam is at least partially transmitted towards an optical output port of the switch. The first and second positions may correspond to complete reflective and complete transmission states, respectively. The mirror may further be positioned in intermediate positions to achieve partial transmission states (and/or partial reflective states), such that the mirror switch operates as a variable attenuator. Embodiments are presented in which the input and output ports are disposed on the same side of the switch, or on opposite sides of switch.

摘要： The invention provides tunable optical filters which incorporate a surface-micromachined out-of-plane plate having a moveable membrane with a high reflective (HR) coated mirror. The mirror defines one side of a Fabry-Perot (FP) filter cavity and is movable in a direction along an axis of the filter cavity. The other side of the filter cavity is defined by a second HR-coated mirror. In one illustrative embodiment, a first plate is formed on a substrate, and then subsequently released from the substrate and secured in a plane orthogonal to the substrate. The first HR-coated mirror is formed as part of a movable membrane supported in an opening through the first plate. The second mirror is formed on a second plate secured in another plane orthogonal to the plane of the substrate, such that the filter cavity is defined horizontally between the first and second mirrors. In another embodiment, the second mirror is formed on an endface of an external fiber, such that light from the fiber can pass from the second mirror through an opening in the second plate to the first mirror. In another possible embodiment, the second plate is eliminated and the second mirror is formed on the substrate. The first plate is then arranged over the second mirror, in a plane parallel to the substrate, and separated from the substrate by spacers, such that the filter cavity is defined vertically.

摘要： An actuation device employing square-loop latchable magnetic material having a magnetization direction (polarization) capable of being changed in response to exposure to an external magnetic field is disclosed. The magnetic field is created by a conductor assembly with non-solenoid configuration. Once the magnetization direction of the material is so changed, the external magnetic field is no longer required to maintain the new magnetization direction. The latchable magnetic material is disposed on the mobile electrode of a switching device, and another magnetic material is disposed in spaced relation to the latchable magnetic material on a stationary electrode or surface. By applying an electrical current to a conductor assembly arranged proximate the latchable material, a magnetic field is created about the latchable magnetic material, to change the magnetization direction and thereby enable the attraction or repulsion of another magnetic material located on the stationary electrode. The resulting relative displacement of the mobile and stationary electrodes effects the selective connection or disconnection of electrical contacts carried on or associated with the respective electrodes of the actuation device without requiring additional power in order to maintain the switched state of the electrodes.

摘要： A switching element according to this invention comprises a photostrictive member. Exposing the member to control light results in a dimensional change in the material. This change is utilized for changing the relative position between an optical fiber and another element, exemplarily a further fiber, a corrugated member, or a mirror, such that signal radiation is directed to a predetermined output port. A variety of exemplary switching elements are disclosed, including interferometric, beam-steering, evanescent field and mode conversion switching elements. Disclosed are also optical communication systems that utilize such switching elements, including passive optical networks.

摘要： Apparatus and method for increasing the concentration of a chemical substance in a fluid comprise a micro-fluidic elongated channel formed in a substrate, with the channel being in fluid-flow communication with an ambient region along its elongated dimension. In general, the fluid includes first and second chemical substances having different vapor pressures. The apparatus includes an evaporation controller for increasing the evaporation rate of the fluid from the channel into the ambient region, thereby increasing the concentration of the lower vapor pressure (LVP) substance in the portion of the fluid remaining in the channel and increasing the concentration of the higher vapor pressure (HVP) substance in the portion of the fluid evaporated into the ambient region.
