  • Publication number: 20040253427
    Abstract: There is provided a composite thin film-holding substrate in which a composite thin film (4) comprising a filler (2) having a refractive index lower than that of a substrate (1) and a binder (3) having a refractive index higher than that of the filler (2) is formed on a surface of the substrate (1). Light is efficiently scattered when passing through the composite thin film (3) which comprises the filler (2) and the binder (3) having different refractive indexes from each other. In addition, the refractive index of a composite thin film (4) comprising a filler (2) having a low refractive index is low. As a result, the discharge efficiency of light which passes through the composite thin film (4) from the substrate (1) to the external is improved.

  • Patent number: 6762553
    Abstract: There is provided a substrate for a light emitting device which includes an electrically conductive and transparent film which is in contact with a surface of a low refractive index member of which refractive index is greater than 1 and not greater than 1.30. In a preferable embodiment, the substrate further comprises a transparent member on its surface which is opposed to its surface which has the electrically conductive and transparent film. There is further provided a light emitting device which includes such substrate and a luminous layer, and the luminous layer is located on the electrically conductive and transparent film. With such light emitting device, a ratio of light which is withdrawn outside through the low refractive index member is increased, so that a coupling-out efficiency for surface emission of light withdrawn into the ambient air is increased.

  • Publication number: 20030174920
    Abstract: An optical waveguide for guided an incident light is formed on a substrate having an electro-optic effect. A first buffer layer is formed to cover an upper surface of the substrate. A conductive film is formed above the first buffer layer. A center electrode and a ground electrode are formed for applying a voltage in order to induce an electric field in the optical waveguide. A second buffer layer is formed between the conductive film and at least one of the center electrode and the ground electrode. The conductive film is formed to be present on at least a part below the ground electrode. A light guided through the optical waveguide is modulated by changing a phase by a voltage applied to the optical waveguide. Thereby, a thermal drift can be effectively restricted so that an optical modulation device having excellent electric characteristics can be realized.
