| 摘 要： | 提出并实施了一种实验推定离子交换单模条波导折射率分布的新方法,给出扩散系数可用常量等效的离子交换条件,导出了条波导离子交换制备过程的两维扩散方程的一般解,拟合推定了离子交换条波导的折射率分布.多波长测试的折射率色散通过引入玻璃色散关系解决,样品测试中表征导模吸收损耗的传播常量虚部由KK变换确定.在此基础上,试制了光纤-条波导-光纤一体化传感器结构,验证实测了多种不同浓度的葡萄糖溶液,最低检测限为0.1 μM,实现了低浓度微量测试,验证了条波导传感机制的有效性. |

| Abstract: | An innovative method that refractive index distribution of single-mode ion exchange is reckoned using an experimental way was proposed and implemented.The key conditions are that a diffusion coefficient must be constant.Then two-dimensional diffusion equation with ion-exchange waveguide was deduced,the presumption of the ion exchange waveguide refractive index distribution of article was fitted.The Lorentz relation solved the optical dispersion problem in sensor test. Experimental results showed that characterization guided mode propagation imaginary part constants of absorption loss by the KK transform.On this basis,the trial of fiber-article waveguide - fiber optic integrated sensor was designed.The glucose concentration was measured and the detection limit was 0.1 μM.The experiments confirmed the validity of the method for a low concentration of trace tests. |
