Abstract

Disclosed is a light amplified Erbium Ytterbium codoped multi-component oxide glass, comprising SiO2, Al2O3, Li2O, Yb2O3, Er2O3, B2O3, Na2O, K2O, CaO, BaO, ZnO, MgO, etc. The raw materials are added into a crucible for melting, then the obtained glass liquid is added into a platinum crucible for melting, clarifying and homogenizing by an optical glass fusion method. The invention solves the problems in the prior art of narrow gain bandwidth, low glass transition temperature, complicated preparing technology and so on. The Erbium Ytterbium codoped multi-component oxide optical glass fiber can provide transmission bandwidth of 60nm and more even gain spectrum, higher glass transition temperature, better chemical and heat stability, can satisfy the increased requirements of the current optical transmission network.

Description

technical field [0001] The invention relates to an erbium-ytterbium co-doped multi-component oxide optical glass for optical amplification and a preparation method thereof. The glass can be used for the third optical communication window, that is, the broadband optical amplifier glass in the 1.55-1.65 μm band. Background technique [0002] Erbium-doped fiber amplifier (EDFA) is widely used in the optical communication field to amplify optical signals in the 1550nm band, wherein the optical amplification medium is an optical fiber doped with erbium ions. However, with the increasing demand for communication services and the rapid increase of Internet information transmission capacity, the information transmission capacity of optical fiber backbone network and optical metropolitan area network is rapidly expanding. The current wavelength division multiplexing (WDM) communication system is difficult to adapt to this demand, Dense Wavelength Division Multiplexing (DWDM) communic...
