摘要:
An organic device has a substrate made of polymer, and a polymer layer adhered on the substrate. A crystallization degree of an adhesive surface with the polymer layer in the substrate is smaller than a crystallization degree of an interior of the substrate. In a manufacturing method for manufacturing an organic device including a substrate made of polymer; and having a polymer layer adhered on the substrate, the manufacturing method includes performing a low crystallization process on an adhesive surface with the polymer layer in the substrate to have a crystallization degree lower than a crystallization degree of an interior of the substrate.

An optical wiring mounted on an electronic device has a light transmission path for transmitting an optical signal. A function layer that reduces friction generated when coming in contact with a structural body in the electronic device to lower than when the light transmission path comes in contact with the structural body, and that bends according to deformation of the light transmission path, is arranged.

A method of manufacturing an optical waveguide device includes providing an optical fiber guide for fixing an optical fiber and optical element placing portions for providing element mounting benches outside a waveguide fixing region of a silicon substrate. A metallic thin film is formed outside the waveguide fixing region of the silicon substrate. After an optical waveguide substrate is bonded to a whole of an upper surface of the silicon substrate through a bonding resin which will become an upper cladding layer, the optical waveguide substrate is diced along an edge of the waveguide fixing region, and the optical waveguide substrate outside the waveguide fixing region is removed to expose the optical fiber guide and the optical element placing portions.

摘要:
An oxide film is formed on an end surface of a waveguide which includes an under cladding, a core and a over cladding. An end surface of a fiber guide holding an optical fiber is coupled the end surface of the waveguide formed the oxide film with a glue. It is preferable that the oxide film is SiOx (1≦x≦1.5). This oxide film has a composition ratio of an oxygen atom smaller than the stable composition, and thus it is easy for OH radicals to appear on the surface of the oxide film. Such OH radicals bond chemically with the resin of the waveguide and the glue. Thus, an adhesive strength between the waveguide and the fiber guide is improved.
摘要:
A light emitting element circuit has a light emitting element, a drive circuit that supplies a current to the light emitting element, and a signal circuit that autonomously supplies a signal according to an ambient temperature. The signal adjusts the current such that the current corresponds to a temperature characteristic of the light emitting element.
