Abstract
Official abstract text for this publication.
An optical module includes a substrate, an optical device including a surface-emitting or -receiving element mounted on a surface of the substrate with a light-emitting or -receiving portion, an optical fiber disposed parallel to the surface of the substrate and in a longitudinal direction of the substrate, a damming member provided between the optical device and the substrate to extend in a width direction of the substrate and dividing a gap between the optical device and the substrate in the longitudinal direction of the substrate into a first portion and a second portion, and a mirror provided at one side surface of the damming member a tip of the optical fiber. The first portion provided on an opposite side to the optical fiber is filled with an underfill resin, and the second portion provided on a side close to the optical fiber is filled with an optical fiber fixing resin.
First claim
Opening claim text (preview).
What is claimed is: 1. An optical module, comprising: a substrate; an optical device comprising a surface-emitting element or a surface-receiving element mounted on a surface of the substrate with a light-emitting portion or a light-receiving portion located to face the surface of the substrate; an optical fiber disposed parallel to the surface of the substrate, and in a longitudinal direction of the substrate; a damming member provided between the optical device and the sub…
