摘要:
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.

A light emission device includes a light emitter, a light reflection member, and a resin sealing the light emitter by covering the light reflection member and the light emitter, in which light deviated from a predetermined front region in the light emitted from the light emitter is totally reflected by a boundary surface of the resin to be forwardly emitted by the light reflection member, and the emitter is thermally contacted with the reflection member to dissipate the heat generated from the light emitter.

An optical read/write head for a magnetic-optic recording and reproducing unit having a beam splitter placed between a collimator lens and an objective lens. The optical path of the beam reflected by a recording disk is bent by the beam splitter and the beam strikes a polarizing beam splitter. The polarizing beam splitter splits the reflected beam into P and S polarized components whose optical axes form n angel of less than 90.degree.. The rays of the P and S polarized components strike respective light detecting elements and which are co-arranged on substantially the same surface.

An optical transmission module has a light-emitting element, a light-receiving element, and an optical path for optically coupling the light-emitting element and the light-receiving element, and transmitting a optical signal. The optical path has a core part, a clad part surrounding the core part, and a support board for supporting the optical path itself and the light-receiving element. A resin part formed of resin having a refractive index higher than air outside the optical path is arranged at a part of a surface area of the clad part along an optical transmission direction to which optical signals are transmitted. The resin part has an inclined surface in which the surface on the opposite side of the clad part is tilted relative to the optical transmission direction. The inclined surface forms an acute angle with the surface of the clad part at the opposite side of the light-receiving element in the resin part.
摘要:
On a front wall of a mold resin (13) sealing a light emitter (12), a direct emission region (18), through which the light emitted from the light emitter (12) directly passes to the outside, and a total reflection region (19), by which the light emitted from the light emitter (12) is totally reflected, are formed. The direct emission region (18) is formed into a shape of a convex lens. A light reflection portion (20) which is made of a concave mirror is provided on the rear face of the mold resin (13). When a part of the light emitted from the light emitter (12) passes through the direct emission region (18), it is affected by the lens to be emitted to the front direction. After another part of the light emitted from the light emitter (12) is totally reflected by the total reflection region (19), it is reflected by the light reflection portion (20) to be emitted to the front direction through the total reflection region (19).
