Abstract

An optical module for connecting a photoelectric conversion device on a substrate to a ferrule connected to an optical fiber includes a body configured to be mounted on the substrate, a first lens disposed on the body at a side thereof connectable to the ferrule, a second lens disposed on the body at a side thereof facing the substrate, and a core disposed in the body between the first lens and the second lens, wherein a refractive index of the core is higher than a refractive index of the body.

First claim

What is claimed is:

1. An optical module for connecting a photoelectric conversion device on a substrate to a ferrule connected to an optical fiber, the optical module comprising:
a body configured to be mounted on the substrate;
a first lens disposed on the body at a side thereof connectable to the ferrule;
a second lens disposed on the body at a side thereof facing the substrate; and
a space formed in the body between the first lens and the second lens, the space being empty and filled with no solid material,
wherein the space turns 90 degrees between a first end thereof facing the first lens and a second end thereof facing the second lens, and both the first end of the space and the second end of the space are closed by walls in the body.

2. The optical module as claimed in claim 1 , wherein the body has inner walls defining the space on which a coating film is formed.

3. The optical module as claimed in claim 1 , wherein the body has a sloped face configured to reflect light entering the space.
