In this paper, a review of numerical methods for design and analysis of nano/micro-sized optical waveguides is carried out. Besides discussing various types of optical waveguides, design of few structures is also presented using FDTD, BPM, and FEM algorithms. Subsequently, few optical devices based upon integration of more than one optical waveguide have also been revealed. Modal effective index analysis and its impact on waveguide designing/signal propagation has also been brought into consideration. Optical waveguides characterization has been carried out by computing second-order and higher order dispersion characteristics, which is vital for information interchange and other nonlinear phenomena. It is anticipated that this effort will help readers in understanding the requirement (subsequently selection) of tools for the design and analysis of optical waveguides.

设计光波导:神话与现实

在本文中,回顾了用于设计和分析纳米/微米尺寸光波导的数值方法。除了讨论各种类型的光波导外,还介绍了使用 FDTD、BPM 和 FEM 算法的少数结构设计。随后,还揭示了基于集成一个以上光波导的少数光学器件。模态有效指数分析及其对波导设计/信号传播的影响也被考虑在内。光波导表征是通过计算二阶和更高阶色散特性来进行的,这对于信息交换和其他非线性现象至关重要。
