| 摘 要： | 本文提出一个改进的获得Ag~+离子交换单模玻璃平板波导折射率分布的方法。由测量不同波长下波导的模折射率,通过反W·K·B方法的最优化数值求解,可以求得折射率分布展开式中的系数。一系列结果表明,这一方法完全适于确定任一单模平板光波导的折射率分布。

| Abstract: | This paper presents an improved approach to obtain the analytical expression of refractive index profile in Ag~+-exchanged monomode planar waveguide. From measured data of mode indices at different wavelengthes, unknown constants in polynominal expansion using inverse W.K.B. approach are determined. The obtained results are perfect well. The presented method can be used for getting index distribution function in any kind of monomode planar optical waveguides. |
