Abstract
A comprehensive modeling approach for elucidating the intricacies of electro-optic (EO) sampling is presented, which fully encapsulates the EO sampling process by accounting for all linear and second-order nonlinear optical effects. The developed approach implements a multi-step procedure, involving a vectorial-field modeling of the second-order nonlinear interactions occurring within the EO crystal, followed by a theoretical evaluation of the subsequent optical EO sampling components. To assess the efficacy of the approach, it is used for the sampling of terahertz electric fields (<1–>60 THz) within the bulk crystals of ZnTe and LiNbO3, as well as a ZnTe-based waveguide. Nonetheless, this versatile method enables the investigation of EO sampling within any crystal incorporated within any geometry. This model provides a powerful tool for the in-depth exploration of EO sampling, paving the way for advancements in various applications.
本文介绍了一种用于阐明电光（EO）采样复杂性的综合建模方法，该方法通过考虑所有线性和二阶非线性光学效应，完全囊括了 EO 采样过程。所开发的方法实施了一个多步骤程序，包括对发生在 EO 晶体内的二阶非线性相互作用进行矢量场建模，然后对随后的 EO 光学采样组件进行理论评估。为了评估该方法的有效性，我们将其用于 ZnTe 和 LiNbO3 块体晶体以及基于 ZnTe 的波导内太赫兹电场（1-60 太赫兹）的采样。尽管如此，这种多用途方法仍能对任何几何形状的任何晶体内的环氧乙烷取样进行研究。该模型为深入探索环氧乙烷采样提供了强有力的工具，为各种应用领域的进步铺平了道路。
