光子晶体是一种新型的光子学材料,具有独特的光子带隙特性,能有效地控制光子的传输状态,可调谐光子晶体的光子带隙的位置和宽度能够随着外部参数的变化而改变,是实现集成光子器件的重要基础,文章介绍了基于有机共轭聚合物材料的非线性光子晶体的超快速可调谐特性。
As a novel photonic material, photonic crystals possess unique photonic bandgap properties and can manipulate the propagation of photons. Tunable photonic crystals, the position and width of whose bandgap vary with the external parameters, are important elements for integrated photonic devices. We report on the development of ultrafast tunable organic photonic crystals based on the excellent optical nonlinearity of organic conjugated polymers.
