    摘要: A spectrometer has a multi-input aperture for admitting an input wavefront and an array of multiple waveguide structures terminating at the multi-input aperture. The input wavefront is incident on each of the waveguide structures, which provide a dispersive function for the input wavefront. Interferometers are formed by elements of the waveguide structures. The interferometers have different optical path length differences (OPDs). The interferometers provide a wavelength responsive output for spatially extended light sources. The output of the interferometers is detected with a detector array. The spectrometer has an improved etendue, and in some embodiments very high resolution.

    摘要: A waveguide cores consisting of a subwavelength grating permits transmission of light without diffraction in a discontinuous manner, wherein the energy is provided by field hopping between subwavelength material segments of higher index. The use of alternating segments permits design of waveguides having desired effective index, mode confinement factor, birefringence, polarization mode or mode dispersions, polarization dependent loss, thermal sensitivity, or nonlinear optical coefficient. An optical system comprises a waveguide having such a core, clad on at least one side, extending between two ends, and wavelength-limiting optical components in optical communication with the ends.

    摘要: A first UDDI registry is queried for at least one entity contained within the first UDDI registry. At least one attribute of the at least one entity contained within the first UDDI registry is compared with an entity attribute record associated with a service registry. If the at least one attribute of the at least one entity contained within the first UDDI registry is different from the entity attribute record associated with the service registry, an updated entity attribute record is generated based upon, at least in part, a difference between the at least one attribute and the entity attribute record.

    摘要: An interface device for performing mode transformation in optical waveguides includes an optical waveguide core for propagating light of a particular wavelength. The optical waveguide core terminates in a subwavelength grating configured to change the propagation mode of the light. The subwavelength grating has a pitch sufficiently less than the wavelength of the light to frustrate diffraction. The device can thus serve as an optical coupler between different propagating media, or as an anti-reflective or high reflectivity device.

    摘要: Methods and devices related to a sensor element for use in the detection and monitoring of molecular interactions. The sensor element uses a silicon-on-insulator wafer optically coupled to a silicon prism. The wafer has a thin silicon film top layer, a silicon substrate layer, and a buried silicon dioxide layer sandwiched between the silicon film and substrate layers. The wafer is coupled to the prism on the wafer's substrate side while the interactions to be monitored are placed on the wafer's silicon film side. An incident beam is directed at the prism and the incident angle is adjusted until the beam optically couples to the silicon film's optical waveguide mode. When this occurs, a decrease in the intensity of the reflected beam can be detected. The molecular interactions affect the phase velocity or wave vector of the propagating mode. Similarly, instead of measuring the incident angle at which optical coupling occurs, the phase of the reflected beam may be measured.
