Patent ID: 7316510

Claim:
An optical module comprising a holding member that holds an optical axis of at least one of two regions that are optically coupled, the holding member having an assembly formed by welding multiple members, one of the two regions being a reference point, one of a first region and a second region on the holding member being a rough adjustment region in which a tilt angle of the optical axis is roughly adjusted through laser irradiation, the other one of the first region and the second region being a fine adjustment region in which the tilt angle of the optical axis is finely adjusted through laser irradiation, the second region being located further from the reference point along the optical axis, the rough adjustment region and the fine adjustment region being defined as regions other than welded portions in which the multiple members are welded to form the assembly and a laser irradiation deformation for adjusting the tilt angle of the optical axis being included in at least one of the rough and fine adjustment regions.
