  • Optical to electrical interconnect structure
    Publication number: 20020105001
    Abstract: A structure for connecting an optical device to an electrical device includes an assembly. At least one electrical connection connects the assembly to at least one transmission line. The distance (or length) of the electrical connection is less than approximately one-fourth of a wavelength of a signal traversing the electrical connection. The present invention fosters also impedance matching between the optical device and the transmission lines.

  • Optical spectrum analyzer wavelength non-linearity measurement system
    Patent number: 6362476
    Abstract: A measurement tool for assessing the wavelength linearity of an optical spectrum analyzer utilizes the linear skirt slope region of the included resolution bandwidth filter. The input wavelength is swept from a predetermined start value to a predetermined stop value, and the associated amplitude is recorded. The insertion loss associated with the system is first determined so that this loss can be removed from the recorded amplitude values. By knowing the skirt slope and the measured amplitudes, the wavelength offset can be determined.
