  • Patent number: 9007677
    Abstract: A wavelength conversion element includes a core formed of a ferroelectric crystal having a periodically poled structure in which first and second domains having mutually inverted directions of spontaneous polarization are alternately aligned side by side, and a cladding covering all side surfaces of the core along a light propagation direction and having a uniform refractive index. Boundary surfaces of the first and second domains are arranged in a non-parallel manner with respect to the light propagation direction.

  • Publication number: 20150069056
    Abstract: A bottle made of polyethylene terephthalate does likely undergo that a gas having a small molecular weight or volatile component escapes from the bottle in a short time in comparison with a glass bottle, steel can, and aluminum can. For a countermeasure, a simple operation prevents hydrogen molecules, helium gas, and volatile component from scattering and being lost. A container filled with gas, or liquid or viscous fluid in which gas is dissolved, or metal granules adsorbing gas is given a cap, and then, the whole of the container including the cap is packed with a metal foil laminated film superior in gas-barrier properties to be vacuum packaged.

  • Patent number: 8922874
    Abstract: An optical amplification device includes a first optical amplification portion, an intermediate portion and a second optical amplification portion. The first optical amplification portion receives input light including signal light and pump light, generates idler light as wavelength converted light based on wavelengths of the signal light and the pump light, and outputs first output light including signal light, pump light and idler light. The intermediate portion outputs second output light, and includes a demultiplexing portion that demultiplexes the first output light into signal light, pump light and idler light, a multiplexing portion that generates the second output light by multiplexing signal light, pump light and idler light, and a polarization plane adjustment portion that exchanges mutually orthogonal polarization components of idler light. The second optical amplification portion amplifies an intensity of signal light included in the second output light.
