摘要

用改进的垂直沉积法在光纤端面制备了高质量的SiO2胶体光子晶体,经过烧结、固化构成胶体光子晶体-光纤结构. 用扫描电子显微镜确定了样品为面心立方密排结构,其密排面平行于光纤基底表面. 利用全光纤传感网络测试了该胶体光子晶体,反射峰中心位于845 nm处,与Bragg理论计算值符合很好. 将该样品浸入不同折射率的液体中,反射光谱的峰值位置随着液体折射率的改变而发生偏移,近似呈线性关系,实现了峰位可调. 对于不同浓度引起的液体折射率的变化,基于光纤的胶体光子晶体结构也能够很好地分辨出来.

Abstract

High-quality three-dimensional nanostructure colloidal crystal-fiber structure is obtained by the modified vertical deposition method. The morphology of the colloidal crystal is examined by the scanning electron microscope, which illustrates that the (111) plane is parallel to the substrate of the fiber end face. The optical characterization of the colloidal crystal is also analyzed with an all-fiber network system. Reflection spectra show the existence of photonic band gap, which is located at 845 nm. As the liquid refractive index filled in the voids of the sample increases, the tunable wavelength of reflected light which is predicted by Bragg's equation with considering the effect of photonic band gap shows a good agreement with experimental results. Also, as the refractive index is changed because of different concentrations of solution, the colloidal photonic crystal-fiber system can also be distinguished by recording the shift of the maximum of Bragg reflection spectra.
