Amplifying apparatus and amplifying medium |
摘要 |
An amplifying apparatus includes an optical fiber that includes a wound portion doped with a rare earth element and three-dimensionally wound, holes being formed in cladding of the optical fiber and surrounding a core of the optical fiber, the optical fiber transmitting signal light injected thereinto; a thermally conductive member in which the wound portion of the optical fiber embedded, the thermally conductive member having thermal conductivity; a light source that emits excitation light; an injecting unit that injects the excitation light emitted by the light source, into the optical fiber; and a temperature adjusting unit that includes a thermal coupling unit thermally connected to the light source and the thermally conductive member, the temperature adjusting unit adjusting a temperature of the thermal coupling unit. |

1. An amplifying apparatus comprising:
an optical fiber including a wound portion doped with a rare earth element and holes being formed in a cladding of the optical fiber and surrounding a core of the optical fiber, the wound portion being three-dimensionally wound and including a first wound portion and a second wound portion wound inside the first wound portion, the wound portion being formed such that a winding direction of the first wound portion and a winding direction of the second wound portion differ from each other by 90°, the optical fiber transmitting signal light injected thereinto; a thermally conductive member in which the wound portion of the optical fiber is embedded, the thermally conductive member having thermal conductivity; a light source emitting excitation light; an injecting unit injecting the excitation light emitted by the light source, into the optical fiber; and a temperature adjusting unit including a thermal coupling unit thermally connected to the light source and the thermally conductive member, the temperature adjusting unit adjusting a temperature of the thermal coupling unit. |
