Abstract: An optical circuit board which is mounted with a loop-back circuit for returning aligning light to the fiber array in the vicinity of the fiber array connection end. Since an aligning loop-back circuit can be formed in an optical waveguide pattern, a production cost does not increase in comparison to an optical circuit board of the related art. The aligning light combined from the optical fiber to the aligning port of the optical circuit board is returned to the optical fiber around the loop-back circuit. Therefore, it is possible to perform alignment using the returned light. That is, alignment can be performed while being mounted on a package without installing a light-reflecting film or mirror.

Abstract: An optical module that is connectable to an optical fiber array and that can be packaged in a high density. Two package modules are mounted on a board, and optical waveguides in a Si photonic lightwave circuit mounted on the package module are connected to an optical fiber array fixed to an optical fiber block. Moreover, output end surfaces of the optical waveguides in the Si photonic lightwave circuit are perpendicular to a mount surface of the package module. The optical waveguides in the Si photonic lightwave circuit may be tilted at an appropriate angle with respect to a direction perpendicular to a right end surface. Moreover, the optical fiber block fixes optical fibers with the optical fibers tilted with respect to a direction perpendicular to an end surface connected to the Si photonic lightwave circuit.

Abstract: An optical module which is connectable to an optical fiber array and which can be packaged in a high density. Two 30 mm square package modules are mounted on a board, and optical waveguides in a 20 mm square Si photonic lightwave circuit mounted on the package module are connected to an optical fiber array fixed to an optical fiber block (15×10 mm). Moreover, output end surfaces of the optical waveguides in the Si photonic lightwave circuit are perpendicular to a mount surface of the package module. In the embodiment, the optical waveguides in the Si photonic lightwave circuit are tilted at an appropriate angle, for example, 20 degrees with respect to a direction perpendicular to a right end surface. Moreover, the optical fiber block fixes optical fibers with the optical fibers tilted at 20 degrees with respect to a direction perpendicular to an end surface connected to the Si photonic lightwave circuit.

Abstract: A flexible substrate having a branch structure in the related art has problems in that: adhesive strength after two bodies are folded and fixed at a bonding region decreases due to an unfolding and opening force at a curve portion and ends of the bonded portions are peeled off and generate gaps; and in a soldering process of the two bodies, the electrodes of one body soldered first are displaced due to reheating in soldering the other body secondly and deteriorate in soldered connection. The present invention provides a new flexible substrate having a branch structure, including first and second bodies joined together, and having a structure in which one of the bodies can be folded back in a longitudinal direction of the whole flexible substrate. Tip ends of the two bodies are provided with multiple electrodes, and are connected by soldering to approximately corresponding positions on both surfaces of an end portion of a printed substrate concerned.

A through-hole is formed through a ceramic resistor accommodated in the focusing pack casing. A fixing hole is formed through the insulating cover in a coaxial relationship with the through-hole. A slider is fixed on a rotatable knob for a variable resistor, which is supported on the focusing pack casing. One of two tongues of the slider is maintained in contact under pressure with a variable resistor of the ceramic resistor, and the other tongue is arranged coaxially with the fixing hole and is maintained in contact under pressure with a wire-shaped output terminal. The terminal is press-fitted in the fixing hole. Another flyback transformer is also disclosed, which comprises a cylindrical holder portion.
