Optical fiber fixing member and manufacturing method of the same and optical module and manufacturing method of the same

An optical module comprising:

• an optical apparatus;
• an optical fiber fixing member having holding portions formed by bending portions defined by incisions formed in a metal member and a fixing portion defined by a remaining portion of the metal member except the holding portions, the holding portions sandwiching an optical fiber from both sides thereof, the fixing portion being used to attach the optical fiber fixing member to a support member;
• a base having the fixing portion of the optical fiber fixing member on a top surface thereof;
• and
• an optical fiber protecting portion that is held by the holding portions of the optical fiber fixing member and that includes the optical fiber inside thereof,
• wherein welding is performed between the base and the fixing portion of the optical fiber fixing member and between the optical fiber protecting portion and the holding portions of the optical fiber fixing member, in a state where a position of the optical fiber and that of the optical apparatus are aligned.

A manufacturing method of an optical fiber fixing member comprising:

• forming bending portions by making incisions in a metal member;
• bending or curling the bending portions to form holding portions to sandwich an optical fiber from both sides;
• and
• forming a fixing portion defined by a remaining portion of the metal member except the bending portions and the holding portions.

A manufacturing method of an optical module comprising:

• forming an optical fiber fixing member by making incisions in a metal member to form bending portions, forming holding portions by bending the bending portions to sandwich an optical fiber from both sides thereof, and forming a fixing portion by a remaining portion of the metal member except the bending portions and the holding portions;
• arranging an optical fiber protecting portion having an optical fiber therein to correspond to the holding portions of the optical fiber fixing member;
• aligning a light axis of the optical fiber with an optical apparatus;
• and
• welding between a base and the fixing portion of the optical fiber fixing member and between the optical fiber protecting portion and the holding portions of the optical fiber fixing member, in a state where a position of the optical fiber and that of the optical apparatus are aligned.
