Abstract
An apparatus and method for cooling an optical fiber, comprising impinging electromagnetic radiation from a laser on an optical fiber comprising a core, in which the electromagnetic radiation is substantially confined, and a cladding, in thermal communication with the core, configured to provide optically activated cooling of the core via the electromagnetic radiation from the laser.

A method of cooling an optical fiber, comprising impinging electromagnetic radiation from a laser on an optical fiber comprising:
- a core, in which the electromagnetic radiation is substantially confined;
- and
- a cladding, in thermal communication with the core, configured to provide optically activated cooling of the core via the electromagnetic radiation from the laser;
- wherein the cladding is a glass or a polymer and comprises a host material and an optically activated cooling material selected from the group of Yb:YLiF4, Yb:NaYF4, Yb:LuLiF4, Yb:KLuF4, and Yb:KYF4, wherein the optically activated cooling material is index matched to the host material.
An optical fiber configured to provide optically activated cooling, the optical fiber comprising:
- a core configured to substantially confine electromagnetic radiation from a laser;
- a cladding, in thermal communication with the core, configured to provide optically activated cooling of the core via the electromagnetic radiation from the laser;
- wherein the cladding is a glass or a polymer and comprises a host material and an optically activated cooling material selected from the group of Yb:YLiF4, Yb:NaYF4, Yb:LuLiF4, Yb:KLuF4, and Yb:KYF4, wherein the optically activated cooling material is index matched to the host material.
