Abstract
A structure includes: an optical fiber including a large-diameter section that is larger in diameter than a remainder of the optical fiber; and a glass block joined to a first end face of the large-diameter section of the optical fiber. The large-diameter section includes a tapering section that: includes, as part of a surface thereof, a sloping surface sloping at an angle of more than 0° and less than 90° to an optical axis of the optical fiber; and is disposed in a portion other than the first end face.
Claims9
A structure comprising:
- an optical fiber comprising a large-diameter section that is larger in diameter than a remainder of the optical fiber;
- and
- a glass block joined to a first end face of the large-diameter section of the optical fiber, wherein
- the large-diameter section comprises a tapering section that:
- comprises, as part of a surface thereof, a sloping surface sloping at an angle of more than 0° and less than 90° to an optical axis of the optical fiber;
- and
- disposed in a portion other than the first end face.

A method of producing a structure that comprises:
- a delivery fiber;
- a small glass tube that covers a section comprising one end face of the delivery fiber;
- and a glass block that is joined to the one end face of the delivery fiber and that is joined to one end face of the small glass tube, wherein the small glass tube comprises a tapering section that comprises, as part of a surface thereof, a sloping surface sloping at an angle of more than 0° and less than 90° to an optical axis of the delivery fiber and that is disposed in a portion other than the one end face, the method comprising:
- inserting the delivery fiber into a small hole in the small glass tube;
- and
- fixing at least part of an inner surface of the small glass tube and at least part of an outer surface of a section of the delivery fiber that has been inserted in the small hole by at least partially heating the small glass tube that has the delivery fiber inserted therein.
