    摘要： An optical shuttle system for routing signals in a communications system that includes a terminal connected to a power source, a shuttle that includes waveguides used for routing the signals, and a beam connected to the terminal and the shuttle so that the beam suspends the shuttle. When power from the power source is applied to the terminal, the beam drives a movement of the shuttle. Furthermore, a method of using an optical shuttle system for routing signals in a communications system, the method includes connecting a terminal to a power source, connecting a shuttle to a beam to suspend the shuttle, and applying power from the power source to the terminal so that the beam drives a movement of the shuttle in a direction substantially perpendicular to a direction of the beam.

    摘要： A mirror for an optical MEMS device has a plurality of segments supported on a substrate layer. Each segment includes a support post, a support layer, and a reflective layer formed over the support layer. The reflective layers of the plurality of segments form the reflective surface of the mirror. Due to the relatively small lateral dimensions of the segments, the mirror has a smaller thermal bow than prior art mirrors. The bow can be controlled, e.g., by appropriately choosing the number of segments and the layer thicknesses.

    摘要： A multilayer micromirror structure that exhibits substantially no form change as a result of a given change in temperature is disclosed. A reflective layer is disposed on a substrate layer, and a counterbalancing structure is disposed on the structure in a way such that a neutral plane is located at a predetermined position relative to the substrate layer and the reflective layer. When forces are exerted at the neutral plane of such a structure, the structure attains a predetermined geometric form. A method of manufacture is disclosed wherein a substrate is etched to define a desired structure and a conformal layer of a masking material is deposited onto the etched substrate. Further etching exposes portions of the substrate and silicon is deposited to achieve another desired structure. Excess material is etched away to free the finished structure and a reflective layer is deposited onto the surface of the structure.

    摘要： The invention relates to devices and methods for detecting a ligand in a liquid, based on deflection of one or more microscopic cantilevers. Each cantilever has an optical waveguide fixed thereto or integral therewith. Deflection of the cantilever is detected by assessing coupling of light between the optical waveguide on the cantilever and an optical waveguide fixed distally thereto.

    摘要： A device structure is defined in a single-crystal silicon (SCS) layer separated by an insulator layer, such as an oxide layer, from a handle wafer. The SCS can be attached to the insulator by wafer bonding, and is selectively etched, as by photolithographic patterning and dry etching. A sacrificial oxide layer can be deposited on the etched SCS, on which polysilicon can be deposited. A protective oxide layer is deposited, and CMOS circuitry and sensors are integrated. Silicon microstructures with sensors connected to CMOS circuitry are released. In addition, holes can be etched through the sacrificial oxide layer, sacrificial oxide can be deposited on the etched SCS, polysilicon can be deposited on the sacrificial oxide, PSG can be deposited on the polysilicon layer, which both can then be patterned.

    摘要： A portable waveguide sensor having one or more gratings. In one embodiment, the sensor has a waveguide, wherein a plurality of grooves imprinted onto the waveguide form a Bragg grating. The surface of the grooves has a functional layer adapted to bind a substance of interest, e.g., a biological pathogen. When the pathogen binds to the functional layer, the binding shifts the spectral reflection band corresponding to the Bragg grating such that a probe light previously reflected by the grating now passes through the grating, thereby indicating the presence of the pathogen. In another embodiment, the sensor has a Mach-Zehnder interferometer (MZI), one arm of which has a resonator formed by two Bragg gratings. The surface of the resonator between the gratings has a functional layer whereas the Bragg gratings themselves do not have such a layer.
