摘　　要：本文提出了一种用胶体光子晶体来装饰单模光纤装饰端面的方法,并说明了这种结构用于相对湿度传感器的原理。研究了用垂直沉积法在光纤端面制备PS(polystyrene)胶体晶体、复合胶体晶体和SiO_2反蛋白石(inverse opal)的技术,用扫描电子显微镜表征了制备得到的胶体晶体及反蛋白石,测量了端面被胶体晶体修饰光纤的反射光谱,并测试了光纤端面复合光子晶体的相对湿度传感特性。提出了一种毛细管-光纤结构,提高了生长在光纤端面处胶体晶体的质量和其机械稳定性。This paper propose a route to decorated end facet of single mode optical fibers with colloidal photonic crystals and present the principle for this structure to be used as relative humidity sensing.The approaches of preparing PS colloidal crystals,composite colloidal crystals,and SiO2 inverse opals on the end faces of optical fibers by vertical deposition was studied.The prepared colloidal crystals and inverse opal were structurally characterized,and the reflection spectra of the photonic crystals-modified microstructure optical fibers was measured.The relative humidity sensing characteristics of composite photonic crystals decorated microstructure optical fibers were tested.Finally,a capillary-fiber structure was proposed to improve the quality and mechanical stability of the colloidal crystals fabricated on the fiber endfaces.
