    • 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.
    • 具有一个或多个光栅的便携式波导传感器。 在一个实施例中,传感器具有波导,其中印在波导上的多个凹槽形成布拉格光栅。 凹槽的表面具有适于结合感兴趣物质的功能层,例如生物病原体。 当病原体与功能层结合时,结合移动对应于布拉格光栅的光谱反射带,使得光栅以前反射的探针光线现在通过光栅,从而指示病原体的存在。 在另一个实施例中,传感器具有马赫 - 曾德干涉仪(MZI),其一个臂具有由两个布拉格光栅形成的谐振器。 光栅之间的谐振器的表面具有功能层,而布拉格光栅本身不具有这样的层。 由于谐振器内的多次反射,耦合到MZI中的光在相对较大的有效传播长度上与结合的病原体相互作用,这导致相对较大的微分相移并因此有利于对病原体的高敏感性。

    • 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.
