摘要： PROBLEM TO BE SOLVED: To reduce influence on a surface of a ferrule from outside.SOLUTION: An optical receptacle 1 includes: a ferrule 2; a sleeve 7 in which a tip of the ferrule 2 is inserted; a metal first holder 4 surrounding and holding the ferrule 2 at a location closer to a rear end side than the sleeve 7; and a metal second holder 5 surrounding and holding the ferrule 2 at a location closer to the rear end side than the first holder, and arranged alienated from the first holder 4. A groove part 9 is formed by the ferrule 2, the first holder 4 and the second holder 5. The groove part 9 is bent at a portion between a bottom face 91 and an opening 92, in a cross section sectioned at a planar surface including an optical axis of ferrule 2. Accordingly, influence on a surface of the ferrule 2 from outside can be reduced.

摘要： PROBLEM TO BE SOLVED: To provide a fiber stub on which a small-size optical isolator element is highly accurately mounted, which is easily processed and has high productivity, and provide an optical receptacle using the same and an optical module.SOLUTION: A fiber stub 4 in which an optical fiber 2 is inserted in the axial direction of a ferrule 1 includes an optical element 3 at a rear end face 1b of the ferrule 1. The projection area of the rear end face 1b to a surface perpendicular to the optical axis is smaller than the projection area of the entire ferrule 1. The rear end-side outer peripheral surface 1e of the ferrule 1 is tapered towards the rear end face 1b. The ferrule 1 has a tapered face tapered towards the rear end face 1b and a small-size optical isolator element 3 can be highly accurately mounted thereon. The fiber stub is easily processed and has high productivity.
