设计了一种胶体光子晶体修饰的光纤.采用恒温快速蒸发法直接在经切割刀处理后的光纤端面生长胶体晶体,再与另一根切割后的光纤在毛细玻璃管中完成对接,制备成胶体光子晶体修饰的光纤.用扫描电子显微镜和光谱分析仪对样品的形貌、结构以及光学特性进行分析.实验结果表明,粒径为640nm、体积分数约为0.5%的SiO2胶体微球溶液在60℃的情况下沉积,大约12h后可得到质量较高的胶体光子晶体.在SEM下,观察到端面的胶体晶体为面心立方(fcc)结构.透射光谱证明,该结构在(111)面上具有光子晶体的带隙性质,带隙中心波长为1383nm。
A colloidal photonic crystal modified fiber was designed.The colloidal crystal was directly grown on the end surface of the fiber after the cutting knife was processed by the constant temperature rapid evaporation method and was then connected with another cut optical fiber in a capillary glass tube to prepare a colloid The morphology, structure and optical properties of the samples were analyzed by scanning electron microscopy and optical spectrum analyzer.The experimental results show that the SiO2 colloidal microspheres solution with the diameter of 640nm and the volume fraction of about 0.5% ℃, the colloidal photonic crystal with high quality can be obtained after about 12h.The colloidal crystal of the end face was observed as a fcc structure under SEM.The results of transmission spectroscopy show that the structure of (111) With photonic crystal bandgap properties, the bandgap center wavelength is 1383nm.
