  • Optical component and dispersion compensation method
    Patent number: 6943951
    Abstract: An optical component of the present invention is compensated its optical dispersion, including third order dispersion, at low loss using optical dispersion compensating element comprising multi-layer film. In the optical component, an optical dispersion compensating element and a functional element are connected in series along an optical path.

  • Optical dispersion compensating device and optical dispersion compensating method using the device
    Publication number: 20040032661
    Abstract: In the past, the occurrence of wavelength dispersion in signals transmitted through optical fibers caused considerable problems in terms of communications at a communications bit rate of 10 Gbps or more, and particularly optical communications at 20 Gbps or more. In order to solve the problems, though various proposals of dispersion compensation method and element have been made for its compensation, any of which did not solve it.
