An optical waveguide amplifier, which can solve the problem of optical attenuation in optical network transmission, is the key technology to solve optical chip integration and optical interconnection. Here, to the best of our knowledge, we propose a novel polymer/silica hybrid waveguide amplifier at 532 nm for the first time. The research is of great significance to the improvement of short distance communication and visible light communication system. The waveguide amplifier was designed as an embedded structure based on : nanocrystals, which were synthesized by high-temperature thermal decomposition. When the input signal power was 0.1 mW, and the pump power was 300 mW, a relative gain of 4.3 dB was obtained on an 8 mm waveguide. This result is of great research significance to break the distance limit and make all-optical transmission a reality.
一种能够解决光网络传输中光衰减问题的光波导放大器，是解决光芯片集成和光互连的关键技术。在此，据我们所知，我们首次提出了一种新型的532纳米聚合物/二氧化硅混合光波导放大器。该研究对于短距离通信和可见光通信系统的改进具有重要意义。该光波导放大器被设计为基于通过高温热分解合成的纳米晶体的嵌入式结构。当输入信号功率为0.1毫瓦且泵浦功率为300毫瓦时，在8毫米长的波导上获得了4.3分贝的相对增益。这一结果对于突破距离限制并实现全光传输具有重大的研究意义。
