摘要
采用高温热分解法合成了粒径约为10 nm的Li:YF4: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Li:YF4:Er,Yb纳米晶掺杂SU-8聚合物平面光波导放大器。当980 nm波长抽运光功率为180 mW时，在1535 nm波长处获得了2.3 dB/cm的相对增益率。
Abstract
With the method of high-tempreture thermal decomposition, Li:YF4: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 Li:YF4: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 mW, a relative optical gain of about 2.3 dB/cm at 1535 nm is achieved in polymer waveguide doped with Li:YF4:Er,Yb nanocrystals.
