摘要：

Thinned silica fibers were fabricated by drawing conventional single mode silica fiber through flame heated method and well-arrayed ZnO nanorods were grown on the thinned silica fibers by a hydrothermal method. The structure enables efficient light coupling between the fiber and the nanorods. With the unique property of high surface to volume ratio of one-dimensional ZnO nanorods, light coupled to nanorods array enhances the optical interaction between the device and the ambient environment. Sensitive humidity sensor was demonstrated by launching laser into ZnO nanorod-covered fibers. Theoretical and experimental results are presented. (c) 2012 Optical Society of America
