Abstract
This optical module has a photoelectric conversion device including a light emitting element, and an optical receptacle for optically coupling an end face of an optical transmission body connected thereto and a light receiving face of a light receiving element. The optical receptacle includes a first optical face on which light emitted from the end face of the optical transmission body is incident, and a second optical face for emitting, toward the light receiving face of the light receiving element, the light incident on the first optical face. An irradiation spot of emitted light from the second optical face on a virtual plane including the light receiving face of the light receiving element is sufficiently large to encompass the entire light receiving face.
Claims6
An optical module comprising:
- a photoelectric conversion device including one or more light receiving elements;
- and
- an optical receptacle to which one or more optical transmission members are to be connected, the optical receptacle being configured to optically couple an end surface of the optical transmission member with a light receiving surface of the light receiving element, wherein:
- the optical receptacle includes one or more first optical surfaces on which light emitted from the end surface of the optical transmission member is incident, and one or more second optical surfaces which allow light incident on the first optical surface to be emitted toward the light receiving surface of the light receiving element, and
- an irradiation spot of light from the second optical surface is large enough to entirely encompass the light receiving surface, the irradiation spot being on a virtual plane including the light receiving surface of the light receiving element.
