Abstract
A sub-mount includes a recess for holding a polymer optical waveguide film and recesses for embedding and holding a light emitting element and a light detecting element. The sub-mount further has an adhesive filling groove formed adjacent to respective recesses. When mounting the polymer optical waveguide film, the light emitting element, and the light detecting element onto the sub-mount, an adhesive is accurately applied and is prevented from flowing out as the adhesive filling grooves are provided.
Claims2
A light transmission and reception module, comprising:
- an optical waveguide film formed with an optical waveguide;
- a light transmitting section having a light emitting element and a sub-mount for holding the light emitting element, that holds one end of the optical waveguide film on the sub-mount so that light emitted from the light emitting element enters into an incident end surface of the optical waveguide;
- and
- a light detecting section having a light detecting element and a sub-mount for holding the light detecting element, that holds the other end of the optical waveguide film on the sub-mount so that light emitted from an emission end surface of the optical waveguide is detected by the light detecting element;
- wherein,
- each sub-mount includes a recess for mounting for embedding and mounting an optical component and an adhesive filling groove formed adjacent to the recess for mounting.
