摘要： An optical micro-electro-mechanical system (MEMS) switch is disclosed. In a preferred embodiment the optical MEMS switch is used as an M×N optical signal switching system. The optical MEMS switch comprises a plurality of optical waveguides formed on a cantilever beam platform for switching optical states wherein the state of the optical switch is changed by a system of drive and latch actuators. The optical MEMS device utilizes a latching mechanism in association with a thermal drive actuator for aligning the cantilever beam platform. In use the optical MEMS device may be integrated with other optical components to form planar light circuits (PLCs). When switches and PLCs are integrated together on a silicon chip, compact higher functionality devices, such as Reconfigurable Optical Add-Drop Multiplexers (ROADMs), may be fabricated.

摘要： An improved waveguide shuttle optical switch design which provides the function of a variable optical attenuator (VOA). A small degree of intentional misalignment of the waveguide will create different levels of optical attenuation. By finely controlling the misalignment of a selected switched position, a single device may be realized that will provide the functions of both switching and attenuating or just attenuation alone. The optical MEMS device utilizes a latching mechanism in association with a thermal drive actuator for aligning a waveguide shuttle platform. The integration of the switching function and the VOA function reduce the optical loss which is otherwise unavoidable when the inevitable alternative of a separate switch and a separate VOA must necessarily be employed. The resultant improved device can also be applied for correcting the difference in optical intensity created by the manufacturing tolerances inherent in the fabrication of array waveguide gratings.

摘要： A thermal actuator comprises a substantially straight beam. The beam has a beam length and a beam mid-point. The beam comprises a plurality of beam segments. Each beam segment has a beam segment width, the beam thus forming a corresponding plurality of beam segment widths. The beam segment widths vary along the beam length based on a predetermined pattern. As the beam is heated by an included heating means, the beam buckles. The buckling of the beam, in turn, causes the beam mid-point to translate or move in a predetermined direction. The beam mid-point movement, in turn, operates an included optical waveguide switch. The heating means comprises any of Joule heating, eddy current heating, conduction heating, convection heating and radiation heating.

摘要： An actuator system that includes two beams that are formed into a diamond pattern. A crossbar is positioned at a midsection to connect the two beams. When power is applied to the two beams, the diamond pattern is driven vertically. An actuator system may also include a substrate and a first layer above a second layer on the substrate. The first and second layers include upper and lower beams joined together at one end of the layers. A method of forming an actuator system includes forming a first layer above a second layer on a substrate, joining the first and second layers together at one end of the layers, and forming upper and lower beams. The upper and lower beams may be different in width, length and thickness to control a vertical movement of the actuator system.

摘要： A thermal actuator comprises a substantially straight beam. The beam has a beam length and a beam mid-point. The beam comprises a plurality of beam segments with beam segment lengths. Each beam segment has a beam segment neutral axis, thus forming a corresponding plurality of beam segment neutral axes. The beam segment neutral axes are offset along the beam length based on a predetermined pattern. As the beam is heated by an included heating means, the beam buckles. The buckling of the beam, in turn, causes the beam mid-point to translate or move in the predetermined direction. The beam mid-point movement, in turn, operates an included optical waveguide switch. The heating means comprises any of Joule heating, eddy current heating, conduction heating, convection heating and radiation heating.

摘要： A thermal actuator comprises a plurality of substantially straight and parallel beams arranged to form a beam array. The midpoint of each beam is attached or coupled to an orthogonal coupling beam. Each array beam has a beam heating parameter with a corresponding beam heating parameter value. The beam heating parameter values vary across the beam array based on a predetermined pattern. As the beams are heated by an included heating means, the distribution of beam temperatures in the beam array becomes asymmetric, thus causing the beam array to buckle. The buckling of the beams in the beam array, in turn, causes the attached coupling beam to move in a predetermined direction. The coupling beam motion, in turn, operates an included optical waveguide switch. The beams in the beam array are heated by any of Joule heating, eddy current heating, conduction heating, convection heating and radiation heating.

摘要： A projection system includes a display apparatus comprising a plurality of tunable Fabry-Perot filters, each of the filters being configured for shifting between a state in which the filter transmits radiation in a bandwidth in the visible range of the electromagnetic spectrum and a state in which the filter transmits radiation in a bandwidth outside the visible range of the electromagnetic spectrum. An illuminator provides light to the plurality of Fabry-Perot filters. A control system receives image data and controls the display apparatus to project an image onto an associated display surface. The control system includes a modulator which provides wavelength modulation signals to the plurality of Fabry-Perot filters to modulate a color of pixels in the image and causes selected ones of the Fabry-Perot filters to shift into the bandwidth outside the visible range to modulate the brightness of pixels in the image.
