中文摘要：

采用LaF3∶Er,Yb纳米颗粒掺杂有机/无机杂化材料作为有源材料,制备了掩埋条形结构光波导放大器,研究了放大器在室温下的增益特性和波导中的频率上转换现象.当抽运功率60mW时,波导中明显可见绿色上转换发光,观测到Er3＋从2H9/2,2H11/2,4S3/2,4F9/2到基态4I15/2跃迁分别对应的4个波长分别为405nm,520nm,544nm和650nm的发射峰,分析了其产生机理.当输入信号光0.6mW,抽运功率160mW时,在1535nm波长处获得1.5dB/cm的相对增益.

英文摘要：

LaF3：Er,Yb nanoparticles doped organic-inorganic hydrid material waveguide amplifier is fabricated. The optical gain and upconversion in the waveguide are studied. The upconversion emission bands at 405,520,544 and 650？nm are assigned to 2H 9/2 → 4I 15/2,2H 11/2 → 4I 15/2,4S 3/2 → 4I 15/2 and 4F 9/2 → 4I 15/2 transitions,respectively. The possible upconversion mechanism of Er 3＋ in this material was analyzed. A 1.55 dB/cm relative gain was observed when pumped by a 976？nm laser at 160 mW power.
