    摘要： A screening system and method are described herein which provide a unique and practical solution for enabling label-free high throughput screening (HTS) to aid in the discovery of new drugs. In one embodiment, the screening system enables direct binding assays to be performed in which a biomolecular interaction of a chemical compound (drug candidate) with a biomolecule (therapeutic target) can be detected using assay volumes and concentrations that are compatible with the current practices of HTS in the pharmaceutical industry. The screening system also enables the detection of bio-chemical interactions that occur in the wells of a microplate which incorporates biosensors and surface chemistry to immobilize the therapeutic target at the surface of the biosensors. The screening system also includes fluid handling and plate handling devices to help perform automated HTS assays.

    摘要： A fiber optic sensor for simultaneously and independently measuring temperature and axial stress. The fiber sensor includes a pair of polarization-maintaining fibers that have known strain and temperature response curves. Each fiber has a plurality of fiber segments in which the elliptical cores are rotated 45° relative to the preceding core segment. Thus, the phase shift induced by temperature or stress in each of the fibers is detected, and the strain and temperature are derived from the detected phase shift. The fiber optic sensor is capable of dual operation. As both a temperature sensor and an axial stress sensor.

    摘要： A polarization-interferometry based tunable periodic filter includes polarization defining components such as polarizing beam splitters or polarizing beam displacers located on the input and output sides of a phase retarder such as a birefringent crystal. A polarization independent input consisting of multiple optical channels having a periodic frequency spacing is converted to a branched output of optical channels in which each branch has a periodic frequency spacing that is different from that of the input, and which are interleaved with each other. The output period is tunable by adjusting the phase delay of orthogonal polarization components. A contrast ratio of ≧20 dB can be realized. The device allows the mux/demux of up to 200 WDM channels with a 50 GHz frequency spacing. Applications of the device include a band splitter, a wavelength selective cross-connect, and a wavelength monitor.

    摘要： A Mach-Zehnder device includes a delay element in one arm which delays propagation of light at a first wavelength relative to propagation of light at a second wavelength. The delay element may be made up of a grating having a period which causes coupling of the first wavelength from a first mode into a second mode. In another aspect, the invention includes a second grating positioned downstream from the first grating and having a period which causes coupling of the portion of light from the second propagation mode back into the first propagation mode. Also disclosed is an optical waveguide in which light at a wavelength &lgr; can propagate in at least a first and a second mode. The waveguide has an effective index of refraction n1 with respect to the first propagation mode of &lgr;, and an effective index of refraction n2 with respect to the second propagation mode. A grating formed in said waveguide and having a period approximately equal to(&lgr;/2)(n1−n2).

    摘要： A sensor system based on Long Period Gratings (LPGs) and a dual-wavelength interrogation scheme for sensing changes in a physical parameter such as temperature or strain. The system comprises a dual-wavelength laser light source, an optical waveguide for propagating the light, a long-period grating disposed in the path of the light, and a detector and processor for correlating a change in resonance wavelength with a numerical value for the physical parameter sensed. Additionally, multiple sensor elements are easily multiplexed by either time-division techniques or optical time domain reflectometry.
