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.

在带有光纤和集成光学元件等指导波光学领域的最新进展包括引入任意形状的光学波导，在许多情况下，这些波导也恰好是任意的不均匀，耗散，各向异性和/或非线性的。大多数这样的波导任意案例并不适合分析解决方案。因此，用于建模和仿真的计算工具对于成功设计，优化和实现光学设备至关重要。该项目的目的是开发用于指导波光学的高级软件包。此处开发的软件包的原型由三个软件包组成，这些软件包反过来挠痒痒，解决和后处理。在求解器单元中，使用标量有限元方法。对本软件包的效率进行了详细检查和评估。
