摘要： Provided is a tunable diffraction grating apparatus including: a diffraction grating portion having a diffraction grating with an linearly variable grating interval, the diffraction grating being formed of an elastic member; a drive portion connected to the diffraction grating portion and applying a force to the diffraction grating portion to vary the grating interval; and a controller for controlling the drive portion to adjust the grating interval depending on a specific wavelength input from the exterior.Therefore, the tunable diffraction grating apparatus can vary a grating interval of a diffraction grating using an elastic material so that a signal of a frequency bandwidth of THz can also be used. In addition, it is possible to simplify structure of the apparatus to reduce the manufacturing cost thereof.

摘要： Disclosed are a single crystal wire and other single crystal articles, and a manufacturing method thereof. The method comprises the steps of: placing into a growth crucible at least one metal selected from the group consisting of gold, copper, silver, aluminum and nickel; heating and melting the metal placed in the growth crucible; growing a single crystal using metal crystal as a seed by Czochralski or Bridgman method; cutting the grown single crystal by electric discharge machining; and machining the cut single crystal and producing a wire or other articles such as a ring. In the method, the grown metal single crystal is cut into a disc-shaped piece by electric discharge machining. The piece is transformed into a single crystal wire or other articles by wire-cut electric discharge machining, and the single crystal wire can be used as a ring, a pendant, or a wire for high-quality cables for audio and video systems. Also, the single crystal formed into the disc-shaped piece by electric discharge machining can be used as a substrate and a target for deposition.

The method comprises the steps of: placing into a growth crucible at least one metal selected from the group consisting of gold, copper, silver, aluminum and nickel; heating and melting the metal placed in the growth crucible; growing a single crystal using the metal crystal as a seed by the Czochralski or Bridgmari method; cutting the grown single crystal by electric discharge machining; and forming the cut single crystal into a wire. In the method, the grown metal single crystal is formed into a disc-shaped piece by electric discharge machining. The piece is formed into a single crystal wire by wire-cut electric discharge machining, and the single crystal wire can be used as a ring, a pendant or a wire within a high-quality cable making a connection in audio and video systems. Also, the single crystal formed into the disc-shaped piece by electric discharge machining can be used as a substrate and a target for deposition.
