Abstract
An optical component of an optical module has a junction surface facing an optical connector and a pair of side surfaces apart from each other in a direction perpendicular to a connection direction of the optical connector. A support member has a pair of sidewalls facing the side surfaces of the optical component respectively and concave/convex portions provided in the sidewalls and concave or convex toward the side surfaces of the optical component. The side surfaces of the optical component are fixed to the sidewalls of the support member via an adhesive, and the adhesive is also applied on surfaces of the concave/convex portions of the sidewalls.
Claims18
An optical module comprising:
- a circuit board;
- a photoelectric conversion element mounted on said circuit board;
- an optical component served for connection with an optical connector attached to an end portion of an optical fiber to optically couple the end portion of the optical fiber and said photoelectric conversion element, said optical component having a junction surface facing the optical connector and a pair of side surfaces apart from each other in a direction perpendicular to a connection direction of the optical connector;
- and
- a support member fixed to said circuit board and supporting said optical component, said support member having a pair of sidewalls and concave/convex portions, the sidewalls facing the side surfaces of said optical component respectively and being fixed to the side surfaces of said optical component via an adhesive, the concave/convex portions being provided in the sidewalls and concave or convex toward the side surfaces of said optical component, and the adhesive being applied also on surfaces of the concave/convex portions.
