中文摘要：

制作了基于KMnF3：Yb^3＋，Er^3＋纳米晶材料的工作波长655nm的聚合物平面光波导放大器。材料的吸收光谱表明，KMnF3：Yb^3＋，Er^3＋纳米晶在980nm附近有很强的吸收。在980nm激光的激发下，由于Er^3＋和Mn^2＋能级之间的能量传递，KMnF3：Yb^3＋，Er^3＋纳米晶产生了很强的红色上转换发光。根据KMnF3：Yb^3＋，Er^3＋纳米粒子的发光特性，制备了KMnF3：Yb^3＋，Er^3＋NCs-PMMA复合材料，用其作为芯层设计了掩埋形结构光波导放大器，利用传统的半导体工艺完成器件制备。器件测试结果表明，当655nm信号光功率为0．1mw、980nm泵浦功率为260mw时，器件获得了2．7dB的相对增益。

英文摘要：

An optical waveguide amplifier at 655 nm based on KMnF3： Yb^3＋ ,Er^3＋ nanocrtstals-PM- MA covalent-linking nanocomposites pumped by a 980 nm laser diode was demonstrated. The ab- sorption spectrum indicates that the nanocrystals have significant absorption at 980 nm. The fluores- cence spectrum was measured under the excitation of 980 nm laser. An optical waveguide amplifier with embedded structure was fabricated using KMnF3 ： Yb^3＋ , Er^3＋ NCs-PMMA nanoparticles as the core layer. A relative gain of 2.7 dB at 655 nm wavelength was obtained when the input signal pow- er was 0.1 mW and pump power was 260 mW in a 1.1 cm-long waveguide.
