- the optical module disclosed in Patent Document 1 aims to provide an opto-electric composite wiring component that is excellent in noise resistance and capable of high-speed, large-capacity, and high-quality information transmission. There is a problem with improvement.
- the inclined surface of the optical waveguide In an optical module that uses the inclined surface of the optical waveguide to guide the light of the optical waveguide to the light receiving element and guides the light of the light emitting element to the optical waveguide as in Patent Document 2, the inclined surface is at the end of the optical waveguide. Therefore, it is common to arrange the light receiving element and the light emitting element side by side. Therefore, since the light emitting element and the light receiving element having a large difference in signal level are arranged in close proximity, suppression of electromagnetic crosstalk and optical (due to stray light) crosstalk in this part has been a problem. . Therefore, conventionally, it has been necessary to take measures such as sufficiently separating the light emitting element and the light receiving element by some method or providing a shield between them. These measures are the reason why the width of the optical module (width in the direction perpendicular to the light traveling direction) must be increased and the structure becomes complicated. It was an obstacle.
- the two-axis hinge is a first axis that opens and closes the folding mobile phone, and a second axis that is perpendicular to the first axis.
- a space through which a signal line in the hinge can pass is a circular hole having a diameter of about 3 mm.
- a plurality of thin coaxial cables are wired in this space.
- the function of the cellular phone is improved, the amount of signal passing through the hinge portion is increased, and the wiring with the coaxial cable is limited.
- the conventional optical module is not sized to pass through a hole having a diameter of 3 mm. Therefore, if a conventional optical module is used, it is necessary to connect the optical fiber and the optical module during assembly of the final product.
- the skill required for the operator differs between the assembly work of the optical component and the assembly work of the final product.
- the optical component manufacturer and the final product manufacturer are different. Therefore, the fact that the optical module is not large enough to pass through a hole with a diameter of 3 mm has been an obstacle to using an optical fiber as an alternative signal line for a plurality of coaxial cables.
- an object of the present invention is to provide an optical module that has a narrow lateral width (a width in a direction perpendicular to the traveling direction of light) and can be reduced in cost.
- an object of the present invention is to provide an optical module that can pass through a hole having a diameter of 3 mm.
- the optical module of the present invention includes an optical waveguide substrate, a light emitting element, a light receiving element, a light emitting element IC, a light receiving element IC, and a plug body.
- the optical waveguide substrate was formed in two optical waveguides arranged in parallel, a light input / output surface formed at one end of the optical waveguide, and at a position separated from each other by a predetermined distance for each optical waveguide. It has two inclined reflective surfaces. That is, the two inclined reflecting surfaces are arranged at different distances from the light input / output surface. Further, the above-mentioned “parallel” is not limited to strictly parallel.
- the above-mentioned “parallel” means that the width of the optical module can be narrowed (a range in which the effect of the present invention can be obtained) and includes a design-acceptable range.
- the light emitting element is disposed at a position corresponding to one of the inclined reflecting surfaces on the optical waveguide substrate.
- the light receiving element is disposed at a position corresponding to the other of the inclined reflecting surfaces on the optical waveguide substrate.
- the light emitting element IC controls the light emitting element.
- the light receiving element IC controls the light receiving element.
- the plug body is formed of a plurality of insulator layers, and the light emitting element wiring pattern between the light emitting element and the light emitting element IC and the light receiving element and the light receiving element IC are formed on different layers of the insulator layer. And a light receiving element wiring pattern.
- the optical waveguide substrate is disposed on the plug body, and is electrically connected between the light emitting element and the light emitting element wiring pattern or between the light receiving element and the light receiving element wiring pattern by a bonding wire or the like.
- the length of the light receiving element wiring pattern may be equal to or shorter than the length of the light emitting element wiring pattern.
- the optical waveguide substrate has two inclined reflecting surfaces arranged at different distances from the light input / output surface, the light emitting element and the light receiving element can be separated without increasing the lateral width. Therefore, optical crosstalk (due to stray light) can be suppressed. Further, the distance can be secured by forming the light-emitting element wiring pattern and the light-receiving element wiring pattern in different layers of the insulator layer. Therefore, electromagnetic crosstalk can also be suppressed. In addition, since an additional component such as a shield is not required, the lateral width (width in the direction perpendicular to the light traveling direction) is narrow, and the cost can be reduced.
- the light receiving element wiring pattern is arranged so that its length is equal to or shorter than the light emitting element wiring pattern, crosstalk to a reception signal having a low signal level can be further suppressed. Improvements can also be made. Furthermore, with the configuration of the optical module of the present invention, it is possible to realize an optical module that can pass a hole having a diameter of 3 mm.
