Fiber optic microsphere with a ZnO thin film for potential application in a refractive index sensor – theoretical study
Abstract
Optical fiber sensors of refractive index play an important role in analysis of biological and chemical samples. This work presents a theoretical investigation of spectral response of a fiber optic microsphere with a zinc oxide (ZnO) thin film deposited on the surface and evaluates the prospect of using such a structure for refractive index sensing. A microsphere is fabricated by an optical fiber tapering method on the base of a single mode fiber. The numerical model is described and simulation was conducted to assess the influence of ZnO layer deposition on a reflected signal. The results indicate that a ZnO film improves the performance in terms of application in a refractive index sensor.
