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.

导波光学领域（例如光纤和集成光学）的最新进展包括引入任意形状的光波导，在许多情况下，这些光波导也恰好是任意不均匀的、耗散的、各向异性的和/或非线性的。大多数波导任意性的情况并不适合解析解。因此，建模和仿真的计算工具对于光学器件的成功设计、优化和实现至关重要。该项目的目的是开发用于导波光学的高级软件包。这里开发的软件包原型由三个包组成，依次进行预处理、求解和后处理。在求解器单元中使用标量有限元方法。详细检查和评估了本方案的效率。
