OPTICAL FIBER, FIBER LASER, AND OPTICAL FIBER MANUFACTURING METHOD |
| 摘要 |
An optical fiber of the present invention includes an uncoated FBG fiber in which an FBG mirror is written in a core glass, a first optical fiber that is spliced to one end of the FBG fiber with a first spliced point interposed therebetween, and a second optical fiber that is spliced to the other end of the FBG fiber with a second spliced point interposed therebetween. The optical fiber of the present invention also includes a collectively recoated portion in which at least the FBG fiber, the first spliced point, and the second spliced point are collectively recoated with a recoat resin having a refractive index less than that of silica, the FBG fiber being sandwiched between the first spliced point and the second spliced point. |

1. An optical fiber comprising:
a FBG fiber which is uncoated and in which an FBG mirror is written in a core glass; a first optical fiber that is spliced to one end of the FBG fiber with a first spliced point interposed therebetween; a second optical fiber that is spliced to the other end of the FBG fiber with a second spliced point interposed therebetween; and a collectively recoated portion in which at least the FBG fiber, the first spliced point, and the second spliced point are collectively recoated with a recoat resin having a refractive index less than that of silica, the FBG fiber being sandwiched between the first spliced point and the second spliced point. |
