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： 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 higher vapor pressure (HVP) substance in the portion of the fluid remaining in the channel and increasing the concentration of the lower vapor pressure (LVP) substance in the portion of the fluid evaporated into the ambient region.

摘要： A package for hermetically sealing a micro-electromechanical systems (MEMS) device in a hybrid circuit comprise a firewall formed on a substrate for the MEMS device and which has a height defining a cavity of the package in which the MEMS device will be sealed. A second substrate spaced from the first substrate hermetically seals the cavity when the second substrate is flip-chip bonded to the first substrate and soldered to the first substrate with a thin film metal material placed on at least a top portion of the firewall. The resulting firewall MEMS device package can be further packaged using conventional CMOS packaging techniques. By hermetically sealing the cavity, the enclosed MEMS device is protected from deleterious conditions found in the environment of conventional CMOS packaging techniques which is often detrimental to MEMS device function.

摘要： Apparatus and methods for a combined optical modulator/photodetector are disclosed. A modulator chip is attached to a photodetector chip using a non-conductive epoxy or solder. The combined modulator/photodetector can be configured in at least two ways. In one configuration, the modulator is located on the upper surface of a chip that is attached, at its lower surface, to a photodetector containing chip. In another configuration, the modulator is located on the lower surface of the modulator chip, which is again attached at its lower surface to the pbotodetector chip. By combining the modulator and photodetector in the manner described above, they can be placed in a single package, resulting in reduced packaging costs versus a separately packaged modulator and a separately packaged photodetector. Moreover, feedback from the photodetector can used to optimize the operation of micromechanical optical modulators.

摘要： A device and method for detecting rotational drift of mirror elements in a MEMS tilt mirror array used in an optical crossconnect. The optical crossconnect directs optical signals from an input fiber to an output fiber along an optical path by rotatably positioning mirror elements in desired positions.

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.
