摘　　要：采用高温热分解法合成了粒径约为10nm的LiYF4…Er,Yb纳米晶,将其掺杂入SU-8聚合物作为光波导放大器的有源层。以SiO2作为下包层,P(MMA-GMA)聚合物作为上包层,制备了LiYF4…Er,Yb纳米晶掺杂SU-8聚合物平面光波导放大器。当980nm波长抽运光功率为180mW时,在1535nm波长处获得了2.3dB/cm的相对增益率。With the method of high-tempreture thermal decomposition, LiYF4：Er, Yb nanocrystals with an average diameter of about 10 nm are synthetized, which are doped into SU-8 and used as the active layer of the waveguide amplifier. The waveguide amplifier based on SU-8 doped with LiYF4：Er, Yb nanocrystals is fabricated by using SiO2 as an upper cladding and P（MMA-GMA） as a lower cladding. For an input signal power of about 0.05 mW and a 980 nm pump power of about 180 roW, a relative optical gain of about 2.3 dB/cm at 1535 nm is achieved in polymer waveguide doped with LiYF4：Er, Yb nanocrystals.
