Abstract
A method of manufacturing an optical module includes the steps of mounting an optical device onto a substrate with a surface on which an optical part is formed facing the substrate, and aligning an optical fiber with the optical part through the substrate. An aligning guide is provided at an end portion of the optical fiber except an end surface facing the optical part. The guide is attached to a guide receiving section, the position of which is determined relatively with the optical device.
Claims22
A method of manufacturing an optical module comprising the steps of:
- mounting an optical device on a substrate in a manner that a surface of the optical device on which an optical part is formed faces the substrate;
- and
- aligning an optical waveguide in a manner to face the optical part through the substrate, the optical waveguide being provided with an aligning guide at an end portion thereof except an end surface facing the optical part,
- wherein the aligning step further includes attaching the guide to a guide receiving section, a position of which is determined relatively with the optical device.
An optical module comprising:
- a substrate;
- an optical device mounted on the substrate in a manner that a surface of the optical device on which an optical part is formed faces the substrate;
- an optical waveguide aligned in a manner that an end surface thereof faces the optical part through the substrate;
- an aligning guide provided at an end portion of the optical waveguide except the end surface facing the optical part;
- and
- a guide receiving section attached to the guide, a position of the guide receiving section being determined relatively with optical device.
An optical transmission device comprising:
- first and second substrates;
- a light-emitting device mounted on the first substrate in a manner that a surface on which a light-emitting section is formed faces the first substrate;
- a light-receiving device mounted on the second substrate in a manner that a surface on which a light-receiving section is formed faces the second substrate;
- an optical waveguide aligned in a manner that one end surface faces the light-emitting section through the first substrate and the other end surface faces the light-receiving section through the second substrate;
- an aligning guide provided at an end portion of the optical waveguide except one of the end surfaces;
- and
- a guide receiving section attached to the guide, a position of the guide receiving section being determined relatively with the light-emitting device or the light-receiving device.
