    • A nanometer size roughened structure is formed on a surface of a light-emitting element, and luminous efficiency is improved.The roughened structure on the surface of the light-emitting element of the invention is formed into the following shape such that the refractive index smoothly changes: (1) the mean diameter of projections on the roughened surface is smaller than the light wavelength; (2) a pitch of the roughened surface is irregular; and (3) positions of the top and bottom of the roughened surface are distributed from their mean values within the light wavelength in order to give a smooth gradient of the refractive index. The surface of such light-emitting element is obtained by forming a thin film on the surface of the light-emitting element using a resin composition which contains a block copolymer or graft copolymer and forms a micophase-separated structure in a self-organization manner; selectively removing at least one phase of the microphase-separated structure of the thin film formed on the surface; and etching the surface of the light-emitting element using the remaining phase as an etching mask.

    • The present invention provides an inorganic separation membrane including a silicalite nanocrystalline layer formed on a porous ceramic substrate, and a porous inorganic protective layer is formed on the nanocrystalline layer. The crystal grain diameter of the silicalite nanocrystal is preferably 150 nm or less, and the thickness of the silicalite nanocrystalline layer is preferably 1.0 to 4.0 μm. The separation membrane may be manufactured by: immersing a porous ceramic substrate in a dispersion solution of silicalite nanocrystals; laminating the silicalite nanocrystals on the surface of the porous ceramic substrate by evacuating the insider of the porous ceramic substrate; forming a porous inorganic protective layer on the silicalite nanocrystalline layer by a hydrothermal synthesis by heating after immersing the porous substrate in a zeolite synthesis solution containing a silica source; and removing organic components in the silicalite nanocrystal by liquid phase oxidation.

    • To provide an optical waveguide and an optical transmitting and receiving module able to perform a transmitting operation and a receiving operation simultaneously, wherein a linearly first waveguide 21 that one side is coupled to an optical fiber 3 and the other side is coupled to a light receiving element 4, and a second waveguide 22 that one side is coupled so as to make an acute angle θ with the side of the first waveguide 21 to be coupled to the light receiving element 4 and the other is coupled to a light emitting element 5 are provided. By controlling a shape of the second waveguide 22, the receiving signal light from the optical fiber 3 is received to the light receiving element 4, and is not guided to the second waveguide 22. Therefore, the receiving operation and the transmitting operation can be preformed at the same time. Namely, when the transmitting optical signal is the incident of light from the light emitting element 5 to the second waveguide 22, the optical signal is guided by the second waveguide 22 toward the first waveguide 21, coupled to the first waveguide 21, and guided toward the optical fiber 3.
    • 为了提供能够同时执行发送操作和接收操作的光波导和光发送和接收模块,其中一侧耦合到光纤3并且另一侧的线性第一波导21耦合到光接收 元件4和第二波导22,其一侧被联接以便使与第一波导21的侧面成锐角的角度θ耦合到光接收元件4而另一侧耦合到发光元件5 提供。 通过控制第二波导22的形状,来自光纤3的接收信号光被接收到光接收元件4,并且不被引导到第二波导22。 因此,可以同时进行接收操作和发送操作。 也就是说,当发射光信号是从发光元件5到第二波导22的光的入射时,光信号被第二波导管22引导到与第一波导21耦合的第一波导21,并被引向 光纤3。
