  • Patent number: 12085836
    Abstract: An optical amplifier of the present disclosure includes a Raman amplification unit and a parametric amplification unit that is configured of a second-order nonlinear element including a PPLN waveguide. In the optical amplifier, second harmonic lights are generated from a fundamental wave light having a wavelength that is slightly detuned to a shorter wavelength side with respect to a phase matching wavelength of the second-order nonlinear element, and is utilized as excitation light for the parametric amplification unit. By utilizing the excitation light based on the fundamental wave light of the wavelength detuned from the phase matching wavelength, a phase matching curve can be obtained in a wide band in a difference frequency generation (DFG) process of the second-order nonlinear element. The reduction in conversion efficiency of the wavelength near the excitation light in the parametric amplification unit is compensated by the Raman amplification unit.

  • Patent number: 6479840
    Abstract: Disclosed is an inventive diode which can reduce a stray capacity to improve various characteristics thereof, in which a dielectric layer, a conductive layer and a second dielectric layer are respectively formed by deposition in this order on an upper face of a semiconductor substrate excluding a central portion of an exposed surface of a P-type region. Then, an anode side electrode is formed extending from the exposed surface of the P-type region to the upper face of the second dielectric layer, and is electrically connected with the P-type region. Herein, the conductive layer is formed such that it is isolated from the electrode by the second dielectric layer, is connected with the semiconductor substrate upper face in a location where the dielectric layer has not been formed, and partially resides in a location sandwiched between the electrode and the semiconductor substrate.

  • Patent number: 6153921
    Abstract: Disclosed is a diode device in which two electrodes of regions forming both terminals are provided on the same face, thereby enabling the device to be connected to a circuit substrate by face-down bonding. Since a region is located within the semiconductor base, an electrode cannot be connected at the top face thereof; to overcome this, a groove is provided extending in a perpendicular direction from the top face of the semiconductor base to the region, and an electrode is provided in the groove. Then, the electrode in the groove is exposed at the top face, enabling the electrodes of both regions to be connected at the top face.

  • Patent number: 6074111
    Abstract: A digital still camera combines a display pattern received from a printing apparatus and a photographed image with each other, and displays the resultant image on a viewfinder. A user adjusts the balance between the display pattern and the image of the object both being displayed on the viewfinder, and depresses a shutter release button. The digital still camera fetches the photographed image. The digital still camera sends to the printing apparatus the fetched image and a pattern name specifying the display pattern used at the time of photographing. The printing apparatus combines the decoration pattern specified by the pattern and the image received from the digital still camera into composite image data. The printing apparatus prints the composite image data.

  • Patent number: 5825075
    Abstract: When a variable capacitance diode device is formed on each of chips obtained by cutting off a wafer, the capacitance values of the diode devices formed on the chips disperse for each wafer due to change in the manufacturing process conditions. To reduced the dispersion in capacitance value of the diode devices, a plurality of variable capacitance diodes (10A, 10B and 10C) are formed on the same semiconductor chip (2) in such a way that the areas of the PN junctions (4A, 4B and 4C) of the respective diodes are different from each other. Further, only one variable capacitance diode (e.g., 10C) which can satisfy a predetermined strict standard is selected and connected to a terminal (11) for use.
