    Abstract: A practical diffractive optical device is efficiently produced at a low cost. A modulated refractive index diffractive optical element comprises a transparent DLC (i.e. diamond-like carbon) film (2) formed on a transparent substrate (1), and the DLC film (2) includes a diffraction grating having a local region (2a) of a relatively high refractive index and a local region (2) of a relatively low refractive index. The DLC film (2) can be easily deposited on the substrate (1) by plasma CVD, and the relatively high refractive index region (2a) in the DLC film can be easily formed by irradiating the film with an energy beam (4) such as an ion beam.

    Abstract: An electrical connection board includes a diamond substrate and an implantation metal layer constituted by the presence of metal elements in the diamond substrate. The metal layer has a thickness of at least 10 nm and a concentration of at least 1020 cm-3 in the diamond substrate. The implantation metal layer is formed by ion implanting metal elements with a high energy level of at least 1 MeV and a high dose of at least 1016 cm-2. Thus, a technique is provided by which a multi-layer electrical interconnection is realized in the diamond substrate having the highest thermal conductivity of all known materials.

    Abstract: The channel add/drop filter includes first and second 2D photonic crystals, and the first 2D photonic crystal includes a first waveguide and a first cavity, with the first cavity acting to take in light of a specific wavelength from the first waveguide and radiate it outside the first photonic crystal, and the second 2D photonic crystal includes a second waveguide with substantially the same characteristics as the first waveguide and a second cavity with substantially the same characteristics as the first cavity. The first and second waveguides are optically connected so that when the principal plane of the first 2D photonic crystal and the electric-field vector of the light within the first waveguide form an arbitrary angle a, the principal plane of the second 2D photonic crystal and the electric-field vector of the light within the second waveguide form an angle of alpha + ( pi /2).

    Abstract: A method and an apparatus for forming a large area of a high-quality diamond film from a microwave plasma by controlling the processing conditions based on the spectroscopic measurement of the plasma emission. In the method of forming a diamond film, a gas mixture of a hydrocarbon gas and hydrogen gas is introduced into a reactor (7), and the gas mixture is excited by microwaves, which are also introduced into the reactor (7), to generate plasma. The light emitted from the plasma is then measured by spectroscopic means. Furthermore, a formation condition of the diamond film is controlled such that the spectrum of a carbon molecule (C2) falls within a predetermined range.

    Abstract: A bonded body of aluminum and silicon nitride firmly bonded to each other which is produced economically, and a light-weight component having an excellent lubrication characteristic as a mechanical component of an internal combustion engine of an automobile. The bonded body includes a base consisting of aluminum as its principal component and a member comprising a silicon nitride sintered body bonded substantially directly to the base. A base material (2) in a powder or bulk form containing aluminum as the principal component and a member (1) comprising a silicon nitride sintered body are put into a mold and are heated under pressure to mutually bond them.
