Abstract: An optical module having a high-moisture-proof package structure in which dew condensation does not occur is provided. An optical module includes optical components including a light source, a pedestal on which the optical components are mounted, a cover which is combined to the pedestal to seal the optical components, and an emitting window disposed in the cover to take light from the light source outside. The pedestal and the cover are sealed with an O ring and a liquid seal material such that a compression direction of the O ring and a compression direction of the liquid seal material are almost perpendicular to each other.

Abstract: The invention provides a wafer-bonded semiconductor device wherein warpage generated when wafers are bonded is reduced at a low cost ad through a simple process. In a method for manufacturing a wafer-bonded semiconductor device by bonding a first wafer substrate and a second wafer substrate together, the method of the invention includes a first step of forming in advance bonding members having a bonding function when heated on the wafer-bonded surface sides of the first wafer substrate and the second wafer substrate, respectively; a second step of supplying flux paste containing two or more kinds of powdery materials having reactivity to the surfaces of the bonding members formed in the first step; and a third step of causing excitation to have the flux paste supplied in the second step start reacting.

Abstract: An optical module in a simple configuration is provided which can suppress optical crosstalk due to leakage light without causing characteristics deterioration and reliability decrease of light-emitting elements to thereby obtain appropriate light receiving sensitivity. In an optical module in which a plurality of light-emitting elements 11 and light-receiving elements 12 are mounted on an optical-element mounting substrate 1, a light-absorbing resin 6 to absorb light with a light-emission wavelength of the light-emitting elements 11 is arranged to cover side surfaces of the light-emitting elements 11 and a non-adhesive layer 7 including a material not adhesive to the light-absorbing resin 6 is arranged between the light-absorbing resin 6 and the optical-element mounting substrate 1.

Abstract: There are provided a downsized and low-cost optical module used as a terminal for wavelength multiplexing optical transmission and one-core bidirectional optical transmission which transmits lights of plural wavelengths through one optical fiber, and a method of manufacturing the optical module. A base on which plural optical elements are mounted, and an optical multiplexer and demultiplexer having wavelength selection filters and mirrors formed on both surfaces of a substrate are prepared. Those two parts are packed into a package so that an optical element mounted surface and a filter surface are substantially parallel to each other, and the optical elements are arranged to emit or receive lights obliquely to the base. With this configuration, because the optical multiplexer and demultiplexer can be mounted in parallel to an X-Y plane, a package can be easily machined by using a lathe, thereby enabling a reduction in the costs.

Abstract: A filter element includes a first glass substrate having a pair of parallel surfaces and a band pass filter arranged on one of the parallel surfaces, a pair of single-crystal substrates (Si wafers) each including a primary surface formed with a depression having an inclined surface with respect to the primary surface occupying at least one half of the opening of the depression, and a second glass substrate having an optical element. The primary surfaces of the single-crystal substrate pair are bonded to a pair of the surfaces of the glass substrate. The depressions are faced through the glass substrate and surround the band pass filter. By this configuration, the filter element can be mass produced with a high accuracy and a low cost by the wafer-level process.
