  • Publication number: 20090297097
    Abstract: An optical switch is provided which includes a plurality of input/output ports for receiving one or more wavelength component(s) of an optical signal. The optical switch also includes an optical arrangement that directs the wavelength component to any given one of the plurality of input/output ports. The given input/output port may be selected from among any of the plurality of input/output ports. If the optical signal includes a plurality of wavelength components, the optical arrangement includes at least one wavelength selective element such as a thin film filter. The wavelength selective element selects one of the wavelength components from among the plurality of wavelength components. The optical arrangement also includes a plurality of optical elements each associated with one of the wavelength selective elements.

  • Patent number: 6862382
    Abstract: A luminescent material, such as phosphor, is radiated by energy propagated from the side of an optical fiber, causing the luminescent material to emit visible light The luminescent material can be of a coincidentally-excited type, requiring the absorption of two wavelengths of radiation to emit visible light. In such a case, two side-emitting optical fibers can be used, with each optical fiber providing one of the needed radiation wavelengths. One embodiment of the invention involves a matrix of optical fibers forming an optical display panel made using coincidentally-excited phosphors. Side-emitting optical fibers are used to simultaneously stimulate a phosphor pixel located between the two fibers, allowing matrix addressing of each pixel individually. The optical display panel is constructed of only optical components. Another embodiment involves an optical switch with coincidentally-excited luminescent material. One radiation is provided by a side-emitting optical fiber.

  • Patent number: 6075240
    Abstract: A hand-held optical scanner for reading color images formed on a document. The scanner head is all-optical and contains no electronics. Optical fiber bundles couple the scanner head to a remote opto-electronic module containing a linear or a 2D sensor array for converting optical signals, reflected from the document, to electrical signals for transmission to a computer display, etc. By using side coupling, the transmitted and reflected light for each pixel travels through the same optical fiber without the need for a beam splitter. The optical fibers are used for the functions of image scanning, position encoding, and signaling a computer which assigns each one of incoherently arranged optical fibers to one of the functions.
