    摘要: An optical signal may be received into orthogonal linearly polarized modes of a transmission optical waveguide, the transmission waveguide including first and second transverse-coupling segments thereof. Optical signal polarized along one polarization direction may be substantially completely transferred from the transmission waveguide into a first transverse-coupled waveguide, the first transverse-coupled waveguide being optically transverse-coupled to the first transverse-coupling segment of the transmission waveguide. Optical signal polarized along the other polarization direction may be substantially completely transferred from the transmission waveguide into a second transverse-coupled waveguide, the second transverse-coupled waveguide being optically transverse-coupled to the second transverse-coupling segment of the transmission waveguide. The optical signals carried by the first and second transverse-coupled waveguides may be combined into a single waveguide. The polarization directions of the transmission waveguide may be rotated about 90° between the first and second transverse-coupling segments.

    摘要: A data structure comprises a clump header table and an inline tree data structure. The inline tree, representing filterable data fields of hierarchically organized data records, comprises an alternating sequence of first-level binary string segments, each followed by one or more corresponding second-level binary string segments. Each clump header record includes an indicator of a location in the inline tree of corresponding binary string segments. A dedicated, specifically adapted conversion program generates the clump header file and the inline tree for storage on any computer-readable medium, and the inline tree can be read entirely into RAM to be searched or filtered. A dedicated, specifically adapted search and filter program is employed to list or enumerate retrieved data records. Run-time computer code generation can reduce time required for searching and filtering. One example includes spatial searching and filtering of data records that include spatial coordinates as data fields.

    摘要: A spectrally-encoded label comprises a spectrally-selective optical element having a label spectral signature. The label spectral signature is determined according to a spectral-encoding scheme so as to represent predetermined label information within the spectral encoding scheme. The label emits output light in response to input light selected by the label spectral signature of the optical element. A spectrally-encoded label system further comprises an optical detector sensitive to the output light emitted from the label, and a decoder operatively coupled to the detector for extracting the label information according to the spectral encoding scheme, and may also include a light source providing the input light for illuminating the label.
