Abstract
To provide a connection structure between an optical element and an optical fiber, which makes it possible to inexpensively secure optical transmission between the optical element and the optical fiber. A connection structure between an optical element and an optical fiber of includes an electro optical element, an optical fiber, and a connecting part. The electro optical element includes an optical surface and a base member provided on the optical surface. The connecting part is coupled to an end surface of the optical fiber and a top surface of the base member.

A connection structure, comprising:
- an optical element including an optical surface and a base member that is formed on the optical surface;
- an optical fiber;
- and
- a connecting part that joins an end surface of the optical fiber and a top surface of the base member.
A connection structure, comprising:
- an optical element including an optical surface and a base member that is formed on the optical surface;
- an optical fiber including a core and a clad;
- and
- a connecting part that joins an end surface of the core and a top surface of the base member.
A connection method to couple an optical element and an optical fiber, comprising:
- (a) forming a connecting part precursor by applying a liquid agent to at least one of an end surface of the optical fiber and a top surface of a base member that is formed on an optical surface of the optical element;
- and
- (b) forming a connecting part by hardening the connecting part precursor while joining the end surface of the optical fiber and the top surface of the base member via the connecting part precursor.
