Embodiment 1

[0036] Preparation of fluorotellurite glass

[0037] The first step: according to the molar ratio of TeO 2 :BaF 2 :Y 2 o 3 (TBY)=70:20:10 Take by weighing 15g of raw materials, put the weighed raw materials into an agate mortar and grind for 30 minutes to make the raw materials evenly mixed; place the mixed raw materials in a 20ml platinum crucible and put Melt in an electric furnace heated to 950°C; after 30 minutes, place the molten TBY glass in a preheated mold, and after the glass is cooled and formed, place it in an electric furnace heated to 380°C for heat preservation and annealing; after 3 hours, close Electric furnace power supply; take it out after the furnace temperature has cooled to room temperature, and the above process is completed in the glove box. The prepared fluorotellurite glass was ground and polished to ~2.5 mm for measurement. Polished samples such as figure 2 shown in the inset.

Abstract

The invention discloses an Er-doped fluorophosphate tellurite glass fiber for fabricating a high-power wideband fiber amplifier. The Er-doped fluorophosphate tellurite glass fiber comprises a fiber core and a fiber coating layer, wherein the fiber core comprises Er-doped fluorophosphate tellurite glass, the Er-doped fluorophosphate tellurite glass comprises the following constituents based on percent by mole: 40-90% of TeO2, 0-60% of BaF2, 0-14.99% of Y2O3, 0.01-10% of Er2O3 and 0-10% of Yb2O3, the fiber coating layer comprises fluorophosphate tellurite, and the fluorophosphate tellurite comprises the following constituents based on percent by mole: 40-90% of TeO2, 0-60% of BaF2 and 0-15% of Y2O3. The matrix glass is founded in a glove box with nitrogen protection, so that low hydroxyl content in the prepared glass sample is ensured, and an optical fiber is prepared by a rod-in-tube method. The fluorophosphate tellurite glass used in the invention has relatively high deliquescence-resistant capability, high erbium ion emission bandwidth and relatively high glass conversion temperature, so that the optical fiber can be used for fabricating the high-power wideband fiber amplifier.

Description

technical field [0001] The invention relates to an erbium-doped special glass optical fiber, in particular to an erbium-doped fluorotellurite glass optical fiber with high water resistance, which can be used to make high-power broadband optical fiber amplifiers. Background technique [0002] Optical fiber communication has the advantages of large capacity, long transmission distance, good anti-electromagnetic interference ability, small signal crosstalk, and good confidentiality performance, making it an important pillar of the "information highway" in today's society. In recent years, with the rapid development of emerging services such as the Internet of Things and cloud computing, the total amount of communication information exchange has increased sharply, and the demand for broadband communication is increasing. This puts forward higher requirements on the working bandwidth of the optical fiber amplifier, the key component in the optical fiber communication system. In ...
