Understanding mechanical and optical responses is significantly important for the development and application of nanowire devices. Hence, special structures are required to provide a level of performance that is adequate for the given application. With this breakthrough, in this work, a model is proposed by combining finite element modeling (FEM) software package ABAQUS and three-dimensional (3D) finite-difference time-domain (FDTD) techniques to measure the strain dependence on the optical behaviors of ZnO nanowire with and without embedding ZnS nanowire and also by the effects of various diameter sizes for the first time. The effects that bending strain have on the optical properties of the material such as electric field intensity and magnetic field intensity have been investigated. The obtained results indicate that the optical characteristics are strongly dependent on the applied strain. In addition, the novel method introduced, is able to furnish a powerful tool for quick comparison between theoretical models and experimental setups for the different properties of nanomaterial, and also should be useful to future predictions for other complex structures. Furthermore, the insights acquired in this study may provide valuable information on the development of robust ZnO nanowire based nanodevices.

了解机械和光学响应对于纳米线器件的开发和应用非常重要。因此，需要特殊的结构来提供足以满足给定应用程序的性能水平。有了这一突破，在这项工作中，通过结合有限元建模（FEM）软件包ABAQUS和三维（3D）有限差分时域（FDTD）技术来提出模型，以测量应变对光学特性的依赖性。 ZnO纳米线有或没有嵌入ZnS纳米线，并且还首次受到各种直径尺寸的影响。研究了弯曲应变对材料光学性能的影响，例如电场强度和磁场强度。所获得的结果表明，光学特性在很大程度上取决于所施加的应变。另外，引入的新方法能够提供强大的工具，用于快速比较理论模型和实验设置，以用于纳米材料的不同特性，并且对于将来对其他复杂结构的预测也将是有用的。此外，在这项研究中获得的见解可能会提供有关坚固的基于ZnO纳米线的纳米器件开发的有价值的信息。
