  • Review of the Status of Optical Fiber Transmission and Integrated Optics

    Publication Year: 1976, Page(s): 16
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (62 KB)

    Since the first low-loss fibers were reported in 1970, optical transmission research has focused almost entirely on the use of fibers. Earlier work on transmission via periodically focused beams had spawned the need for integrated optics -- using single-mode optical circuitry in miniature dielectric waveguides -- in order to make feasible multiple carrier transmission medium. In both of these two ... View full abstract»

  • Theory for Electrooptical Grating Modulators

    Publication Year: 1976, Page(s):24 - 26
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (171 KB)

    A popular configuration for electrooptical modulators used in integrated optics consists of periodic electrodes placed on the surface of a thin film waveguide made of electrooptical material. When voltages are applied to the electrodes, the thin film guide becomes spatially modulated with periodicity equal to that of the electrodes. Guided light is diffracted after passing through the modulated re... View full abstract»

  • Network Methods for Dielectric-Grating Applications

    Publication Year: 1976, Page(s):27 - 29
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (218 KB)

    The application of network methods to the analysis and design of integrated-optics components is illustrated for the case of dielectric gratings, which are relevant to optical beam couplers, filters and distributed-feed-back lasers. The advantage of the network representation in those cases is that the role of each grating parameter can be interpreted in terms of the network elements. In addition ... View full abstract»

  • An Ideal Refractive-Index-Distribution and Mode Filter for Band Broadening of Multimode Optical Fiber

    Publication Year: 1976, Page(s):30 - 32
    Cited by:  Papers (1)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (233 KB)

    The focusing fiber whose refractive index distribution has the valley at the periphery of the core, as the ideal index distribution with respect to the bandwidth, is analyzed exactly, by which the group delay spread caused by the core-cladding boundary can be eliminated, and, therefore, the bandwidth can be broadened.

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (158 KB)

    Several integral relationships are presented for commensurate transmission-line networks. The integrals focus on the face that Z(1) for such networks, where Z(S) is the input immittance of the network, is associated with a real or redundant unit element prefacing the network. Three bandwidth restrictions are derived. Some applications of the integral relationships are presented. View full abstract»
