  • Publication number: 20210036781
    Abstract: An optical node device includes: a multicore optical amplification unit that amplifies collectively light transmitted along a multicore fiber; a separation unit that inputs the amplified light in each core to each of a plurality of input-side single-core fibers; an optical cross-connect switch that attenuates the light input from each of the plurality of input-side single-core fibers through an optical attenuator, separates the light in accordance with a wavelength, and outputs the separated light to an output-side single-core fiber of a plurality of output-side single-core fibers related to a respective output destination; a plurality of single-core optical amplification units that amplify the light transmitted along the corresponding output-side single-core fibers; and an output unit that outputs the light transmitted along each of the plurality of output-side single-core fibers to a multicore fiber.

  • Publication number: 20200381888
    Abstract: An optically amplified repeater system includes optical transmission paths, a multi-channel optical amplifier, one or more Raman amplification pumping light sources, and a wavelength multiplexer. The multi-channel optical amplifier includes K simultaneous pumping light sources, N optical amplification media, and one or more optical couplers, and simultaneously amplifies, with the K simultaneous pumping light sources, light intensities of optical signals that pass through the N optical amplification media and propagate through the optical transmission paths. Light intensities of the wavelength band of the optical signals is Raman amplified by the Raman amplification pumping light. A light intensity of the Raman amplification pumping light output from the one or more Raman amplification pumping light sources is determined in accordance with characteristic differences between the optical signals passing through the optical transmission paths.

  • Publication number: 20200309869
    Abstract: To provide a magnetic sensor element and a magnetic sensor device that can be easily manufactured and can reduce a loss of light to the extent possible. The above-described problem is solved by a magnetic sensor element comprising a planar lightwave circuit (11) provided with a light branching part (12), an input optical fiber (19) and an output optical fiber (20) connected to the planar lightwave circuit (11), a metal magnetic body type light transmitting film (30) that is provided on one end surface of the planar lightwave circuit (11) and transmits light entered from the input optical fiber (19), and a reflecting film (40) that is provided on the metal magnetic body type light transmitting film (30) and reflects the transmitted light. The output optical fiber (20) is a polarization-plane maintaining optical fiber, and the input optical fiber (19) and the output optical fiber (20) are aligned and connected to the planar lightwave circuit (11).

  • Patent number: 10665445
    Abstract: A sample loading plate that includes at least one sample mounting spot that mount a sample thereon is provided with a substrate having a conductive surface and an insulating film that is laminated on the conductive surface of the substrate and that has at least an insulating surface, the insulating film being sparsely formed so that the conductive surface of the substrate is partially exposed at least in the sample mounting spot. Thus, a voltage applied to the sample loading plate can effectively place the sample in an electric field. As a result of which, in a mass spectrometric analysis of the sample, there is no charge up of the sample and appropriate ionization becomes possible.

  • Patent number: 9799501
    Abstract: A sample mounting plate has: a substrate made of alumina ceramic which exhibits white; and a cover layer which is laminated so as to cover the front surface of the substrate and which has multiple grooves formed in some areas. The cover layer has: a conductive interference layer which exhibits conductivity and is configured so as to exhibit a prescribed color (such as navy blue) through light interference and which is laminated on the substrate; and a water-repellent layer which exhibits higher water repellency than that of the substrate and is laminated on at least a part of the conductive interference layer and on which a sample is to be mounted.
