Abstract

The invention belongs to the technical field of ultra-wide-band, special optical fibers and optical appliances, and particularly relates to a fluorotellurite er-doped optical fiber. The fluorotellurite er-doped optical fiber consists of a fiber core and a coating layer coated at outside of the fiber core; the fluorotellurite er-doped optical fiber is characterized by being prepared by mole TeO2: ZnF2: Na2CO3, Er2O3; the coating layer is prepared by a third raw material with the mole ratio of TeO2: ZnF2: Na2CO3=(53-57): (33-37): (4-6); the diameter of the fiber core is (5.0+/-0.4) miu m; the diameter of the coating layer is (125+/-0.5) miu m. The invention further discloses a preparation method of the optical fiber, a terminal formation method and an ultra-wide-band optical fiber amplifier with the optical fiber. The fluorotellurite er-doped optical fiber has a softer optical fiber signal channel with wider band width, flatter gain, and more storage, and can reduce the input of light devices, greatly reduces the system cost, and others.
