Recent advances in the field of guided-wave optics, such as fiber optics and integrated optics, have included the introduction of arbitrarily-shaped optical waveguides which, in many cases, also happened to be arbitrarily inhomogeneous, dissipative, anisotropic, and/or nonlinear. Most of such cases of waveguide arbitrariness do not lend themselves to analytical solutions ; hence, computational tools for modelling and simulation are essential for successful design, optimization, and realization of optical devices.The purpose of this project is to develope a high-level software package for guided-wave optics. A prototype of the software package developed here consists of three packages tickling the pre-processing, solving, and post-processing, in turn. In the solver unit the scalar finite-element method is used. The efficiency of the present package is examined and assessed in detail.

在诸如光纤光学和集成光学的导波光学领域中的最新进展包括引入任意形状的光波导，其在许多情况下也恰好是任意不均匀、耗散、各向异性和/或非线性的。大多数这样的波导任意性情况不适合于解析解，因此，建模和模拟的计算工具对于光学器件的成功设计、优化和实现是必不可少的。本项目的目的是开发一个高级的导波光学软件包。本文开发的软件原型由前处理、求解和后处理三个程序包组成。在求解器单元中采用标量有限元方法。对当前一揽子计划的效率进行了详细的审查和评估。
