Abstract: 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.

Abstract: 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. Due to multiple reflections within the resonator, light coupled into the MZI interacts with the bound pathogen over a relatively large effective propagation length, which results in a relatively large differential phase shift and therefore advantageously high sensitivity to the pathogen.

Abstract: An optical displacement sensor is disclosed that provides a high signal-to-noise ratio output signal without some of the disadvantages for doing so in the prior art. An embodiment of the present invention directs a light beam toward a Fabry-Perot interferometer and detects both the reflected and transmitted optical beams that result from interaction with the Fabry-Perot interferometer. Signal processing techniques are applied to signals based on both the reflected and transmitted beams, resulting in higher signal strength and/or reduced noise in the resulting output signal.

Abstract: An apparatus and method for estimating a parameter of interest using a force responsive element comprising, at least in part, a balanced material. The balanced material is temperature insensitive over a specified range of temperatures such that the force responsive element may estimate the parameter of interest by responding to a desired force with relatively little interference due to temperature changes within the specified range of temperatures.

Abstract: The illustrative embodiment of the invention is a tunable nanomechanical near-field grating capable of varying the intensity of a diffraction mode of an optical output signal. In accordance with the illustrative embodiment, the tunable nanomechanical near-field grating comprises a first and second sub-grating, each sub-grating having line-elements with width and thickness less than the operating wavelength of light with which the grating interacts. A plurality of lateral apertures is formed by the two sub-gratings, each aperture comprising the space between one line-element of the first sub-grating and at least one line-element of the second sub-grating. One of the first or second sub-gratings is capable of motion such that at least one of aperture width and aperture depth changes, causing a perturbation to the near-field intensity distribution of the tunable nanomechanical near-field grating and a corresponding change to the far-field emission of the tunable nanomechanical near-field grating.
