Method for manufacturing optical component and pressing jig

A method for fabricating an optical module comprising:

• an optical module having a cylindrical receptacle that holds the first optical fiber and has a first flat surface parallel to the optical axis of the first optical fiber as an outer surface;
• an optical fiber holding member in a cylindrical shape, that holds a second optical fiber that is optically coupled to the first optical fiber and has a second flat surface parallel to the optical axis of the second optical fiber as an outer surface;
• and
• a clip member having a third flat surface in surface contact with the first flat surface and the second flat surface for aligning the first optical axis with the second optical axis, the clip member being configured to press the receptacle and the optical fiber holding member against each other;
• comprising steps of:
• preparing the optical module and the optical fiber holding member;
• attaching the clip member to the receptacle of the optical module and the optical fiber holding member;
• and
• pressing the receptacle of the optical module and the optical fiber holding member from below and pressing the clip member from above;
• wherein the pressing step has pressing the first flat surface of the receptacle and the second flat surface of the optical fiber holding member at the third flat surface of the clip member, and which performed until the first flat surface of the receptacle and the second flat surface of the optical fiber holding member establish parallelism with the third flat surface of the clip member by using a jig that changes the parallelism of the pressing surface.
